Black rectangles when zooming.

    Mark,

    Have you already tried setting the Preferences for Hardware Acceleration to "None" to see what happens?

    If it makes a difference you could try a process to force a regeneration of the kernel used to drive the GPU as activated by C1.

    Thanks for the info, appreciated.

    From some further testing it appears to only manifest itself when zooming in and out of .tiff files. It's almost like the rendering is being told to stop before it has fully completed! 

    I have tried changing the Hardware Acceleration (use OpenCL for) options for both Display and Processing and this does not seem to have any positive effect on the black rectangles.

    It will be interesting to learn if others experience this with .tiff files.

    Are these particularly large TIFF files? In Mb terms rather than dimensions per se.

    Did the Hardware acceleration field in the preferences have a message below to the effect that Acceleration was being used?

    I ask because on my system the first run of a new install (as identified by C1) fails to create the required GPU kernel.

    The reason is that the process first detects the on-board Intel CPU capability and starts to test that followed by the NVidia GPU.

    The Intel assessment, since a few months ago, fails at about 93% complete due to some bad parameters or something, and process stops. The Quadro assessment does not complete.

    Closing and restarting C1 the process runs again, skips the Intel assessment as knows if failed previously, runs the NVidia assessment successfully, builds the kernel and set the text to indicate that Acceleration is in use.

    Assuming that your black patches are temporary and would not appear on exported images it's just possible that what you are seeing is a slower than previously screen output building and rendering using a slower process (on a big file) then you have been used to working with. Your description of black rectangles sort of fits with the way screen processing works. So it is one possibility  - but there almost certainly others.

    If you don't stumble across anything at all that seems to make a difference I would suggest that you use the "Submit a request" link fond on many community pages and elsewhere to create a Support Case and get the C1 support team to take a look at it for you.

    Hi Grant,

     

    The TIFF file size is around 100MB in size.

    The Hardware Acceleration field displays underneath it "Capture One is using hardware acceleration"

    I have installed and removed the software a couple of times, there does not seem to be a problem with the install.

    I have also rolled back to version 13.0.3.19 and the graphics worked perfectly including the .TIFF files.

    Please note on the latest version this behavior is inconsistent when zooming in and out of a .TIFF file, sometimes it works fine and other times the black rectangles will appear.

    As it's only on the .TIFF files that I generate from a round trip to Affinity Photo I can live with this random rendering.

    Thanks for your help.

    Mark.

    Hi Mark,

    In that case I think what you are seeing is simply the system dealing with a lot of processing.

    Internally the amount of data being handled will be much more than 100Mb as the tiffs are likely to split into multiple parts depending on whether 8 bit or 16 bit, each part processed and then stitched back together. (A crude description but probably enough.) The presentation to screen then requires further "blocks" of processed data to be positioned and blended ready for viewing. If some parts of the overall process get slightly delayed in the work queue the building of the patchwork becomes more readily visible.

    Your description sounds like that sort of resultant display writing anomaly  - not unlike TV images can be if there is some sort of signal limitation problem or an internal component is starting to show signs of faults.

    If the ultimate result and output is OK then I doubt there is a software fault. If you see strange results for an image and they are always there, including in any output files then the changes are that there is either an application fault or some aspect of an internal component for the hardware - quite often the software that drives the graphics processing device being used at the time - has some issues for some reason.

    Why the problem should present more erratically using the latest version is an interesting question but an answer would probably require a deep dive into the changes n the engine to accommodate new functionality AND and assessment of whether the effect is different depending upon the editing undertaken and the application features and functions being used and system configuration.

    That could be more than a little time consuming!

     

    HTH.

    I too am seeing weird black rectangles when zooming in. I seem to experience the issue ONLY when I have a heal layer. If I toggle the heal layer on and off while zoomed in, the black rectangles will appear and disappear. Pretty sure I only started seeing the behaviour with the most recent update 13.1.1.31. Also, doesn't make any difference if I have hardware acceleration on or off.

    Simon.

    I have seen this with heal layers of old images which were created with on older version. Not rectangles but black or white circles though. They appear for a fraction if a second and then they are gone. Not seen this with new layers but haven't done many with the new version.

    Edit: with raw files, btw.

    I'm having the same issue. I get black rectangles when I zoom in.  I am using the heal brush.  My raw files came over from Capture One 11. The issue goes away if I delete the heal layer. .... Oh, I'm also getting it with a clone layer. .. Once I upgraded from trail to full license and upgraded the Engine under Base Characteristics, the problem went away!

    I've tried importing into a brand new catalog and brand new session, still get the black rectangles. It also seems more likely to happen if I have a colour or clarity adjustment on the image. If I zoom in, experience the black rectangles, then reset the clarity panel for example, the black rectangles usually disappear (although the image brightness still appears incorrect until I zoom out again)

    Not sure if I can post a link in the forum, but I made a screen recording of it happening:

    Simon, if you are pretty sure you did not see these triangles before the latest update, you can easily go back to 13.1.0 without loosing much if any enhancements. I had to because of another bug and in Windows, I was able to simply install the previous release on top of the current release. No uninstalls required.

    Thanks Kevin, I may give that a try. I'm doubting my own memory now on the specific build number, but I'm positive I didn't see this issue with earlier builds of C1 20 / 13.

    Simon,

    I think you need to allow some time for your system to catch up with your changes as you edit and zoom.

    SFA I assume you're referring to my video? I was zooming in and out to demonstrate the effect. The black rectangles and display corruption don't go away. It's not a question of waiting, they are permanently on screen until I zoom out or disable the heal layer.

    Simon,

    That was not so obviously the message from your video.

    It looks like the process is stalling at some point and not completing a display update. Sending another instruction (switch layer on or off, change a tool value, etc.) kicks it into life again.

    Daniel's comment (above) about only seeing that sort of problem with images previously processed in an earlier version (V11 processing engine in his example) is an interesting but not entirely unexpected situation given the big change to the approach  taken with the latest Heal and Clone layer functionality.

    I'm running an 8 year old notebook with Win 7 and sometimes see temporary stutters, especially if all the applications running have used up most of the RAM available. Nothing like your video though.

    That sort of suggests that the source of your problems, whatever it is and wherever it originates, has some local to the system effects in play. Having tried what you have tried already I would suggest that you create a support case using the "Submit a request" feature in these pages and get the C1 support team to take a look into it.

    Comparing system specs and log files is probably something for which they have far more useful knowledge available than might be randomly found in this somewhat self selecting forum. Just resist any "standard" advice, like uninstall then re-install, if you have already done so!

    Has there been any fixes found for this? I'm getting the black rectangles when zooming in images with a heal layer. It happens on both TIFFs and Fuji RAW files, and started when I updated just recently to 13.1.2.35. I'd be happy to roll back to the previous version until a fix is issued, but I no longer have that install file and don't see a place to download it.

    Michael,

     

    This seems to be the advisory document related to your needs. First paragraph of the Answer.

    Exactly same blocking issue using Heal or Clone layers on both .RAF and (8-bit)TIFF. doesn't matter whether CL is on 'Never' or not.  Even after GPU kernels are re-built.

     

    Changng preview size does not fix it, re-building previews doesn't fix it.

     

    Have raised a call with C1. If anyone found an answer. I'd love to know.

     

    GPU in Task Manager not going much above 30-40% at peak, so its not a max-out issue.

    No fix yet. C1 support told me a few days ago they're still working on it. I suspect what this means is that it will be fixed in the forthcoming v21 release, so in we'll have to pay for the bug fix.

    same problem here with the 21 version - black rectangles when zooming images taken by Nikon Z7

    So far v21 seems to have resolved the issue for me.

    I am having same problems as Simon. C1 20 Fuji. Started just after using healing function. I'm new to C1 and not very techy. Will follow this thread.

    If you have an NVidia Graphics card check the driver version compared to the latest offering.

    If it IS the latest version try the one before.

    If it is not, try a later one.

    In EITHER CASE select a "Studio" version of the driver - there are at least 2 development threads for different processing objectives with NVidia drivers - and see if that improves things.

    You may be able to run the checks using an application provided by your hardware manufacturer.  Or the update may have come via Windows.

    There are no guarantees following this advice will solve the problem but it's worth considering if only to eliminate it!

    C1 support confirmed to me months ago that this is a bug in their software not a hardware issue. They're currently refusing to comment on whether they will bother to fix it in C1 v20 ..... However for me at least, the bug does seem to be fixed in C1 v21. I no longer the the black rectangles with heal layers on Fuji files after I upgraded to v21.

    Same issue here with a DNG file that was originally created in Lightroom and occasionally with Fuji RAW files. I can also confirm that the issue occurs as soon as a healing layer is active. When I disable the layer the image is displayed correctly.

    In addition I have the problem that every now and then JPEG exports from Fuji RAW files come out corrupted - even with hardware accelaration switched off. I only switched from Lightroom to Capture One three months ago and it is quite frustrating to get such a buggy piece of software, which has issues with the most basic functions. For me this makes it hardly useable. 


    Back to this topic, here is an example with the healing layer inactive:

     

    And the same with the healing layer activated:

    I had similar problems with 8-bit TIFF files exported from PtGui using PACKBITS compression. Exporting with no compression or LZW solved the issue for me. Converting PACKBITS to ZIP via Affinity Photo as well.

    This might not solve all these kind of effects issues, but playing with the file format might provide a solution for some of the cases.

    I'm facing this issue in C1 v23, so it looks like the issue was never resolved. Been facing it in one guise or another for many months now.

    Standard Canon RAW CR3 files, all 45-50Mb. Latest NVidia Studio driver (plus every version released over the last year). NVidia GPU control panel settings all set to point to the GPU for C1 (the default is not this in some settings, remarkably!).

    Opened several related tickets with C1 support over the last year or so, with no resolution given.

    I'll raise another, but wondered if anyone managed to resolve this issue yet?

    Thanks much
