Black horizontal bars on edit screen when moving sliders

    Appearing and staying on screen or as a temporary glitch?

    Have you updated your OS recently? Or any other system activity that might have coincided with the appearance of the problem?

    As a quick test try turning off the Setting for "Use Hardware acceleration". (See Preferences.)

    Does the problem go away?

    When I click the slider they appear for a few seconds then disappear.  If I click a different slider it happens again and then disappears.  My OS is at 11.4 Big Sur. I do have an update for 11.6 I can try tonight.

    The "Use Hardware acceleration" feature has two settings and both are set to AUTO.  I turned them to Never (the only other option) and closed and reopened Capture One.  This did not make a difference.

    What computer and OS? It sounds like it's taking the computer a little time to compute the adjustments. If what you're seeing is momentary I wouldn't worry about it. If you want to get an idea of whether it's taking the computer some time to catch up with your slider settings, install something like MenuMeters, Stats (both freeware) or iStat (shareware) and set it to show CPU and GPU utilization (RAM and other parameters are also useful). I've found that whenever I see temporary things like you report, my monitoring apps (MenuMeters and iStat) show the GPU working pretty hard, and GPU activity drops coincident with the display artifact going away.

    For reference, this happens on a 2018 MBP with a fast i9 processor and also on a 2012 Mac Pro with 12-core 3.46 GHz processors and 64 GB of RAM. Both are very fast machines.

    Thanks for your thoughts, Abbott.  The problem only happens when using Capture One 21 Pro.  Lightroom and Photoshop are no problem.  I am only utilizing 759 GB of 1 TB drive.  It is a Mac 2019 Retina 5K, with Radeon Pro 570X 4 GB and OS version is 11.5.2.  I use 2 external G Drive hard drives for my photos and documents.  

    I have an OS update to do this evening.  So I will post an update tomorrow if that fixes anything.

    Thanks,

    Hi LuAnn,

    Sounds like you safely turn hardware acceleration back to Auto (On).

    I'm on Windows and have only very rarely seen that sort of display issue but slowness and stuttering can be evident if the system is busy and especially if it is running low on available memory (multiple applications running) or disk space.

    Are you by any chance using a 4k or 5k screen?

    Ah, our posts crossed.

    Driving the 5k screen will require a lot of processing and internal data shifting capability.

    I'll leave it to other Mac users to offer their observations on that topic.

    Thanks to everyone for your thoughts on this problem.  I had a software upgrade ready to go on my Mac and after updating to the latest version of Big Sur the problem went away.  I don't know what the fix was but everything works fine now.

    Perhaps a GPU driver update?

    Or maybe just a general "refresh" sorting out some internal anomalies created during regular use.

    Computers, one has to love them ... sometimes.

    Abbott, I'm afraid they were fast machines before OS 11.x :(

    After the Safari update yesterday I had 3 C1 crashes when I added crop parameters to not more than 10 images by using the diagonal double arrow to copy adjustments. Cropping simply doesn't work simultaneously on multiple images. No matter if "edit main variant" or "edit all chosen variants is active". I'm pretty sure I could provoke crashes although I'm not the fastest to edit, but C1 appears to stumble constantly over it's own "background processing" feet.

    And DxO, which never had a problem to work on all chosen variants simultaneously, even with cropping, and never crashed (neither on 10.14 nor on 11.5) also shows black squares after editing a few images. They go away when choosing a different image. And it is still not crashing. Yet. But getting slower. And there was no other update from DxO or Capture One, so I'm pretty sure this time it's not C1's fault. But crashing became the new "normal" for C1.
