Corrupted exports
Since about 3 weeks capture one has been randomly corrupting exports to either tiffs or jpgs.
For example when creating a tiff file for denoise plug-in.
The created tiff will have several dozen squares filled with gray noise. It also does this randomly for jpg exports regardless of quality settings. It is random, so maybe 2 or 3 out of 30 or 40 exports.
For full quality, one hint is that the created jogs images are a 100mb instead of the usual 25 to 35 mb range.
While these are easy to see, a far worse one is exporting to full size 100% quality jogs where it ainstead of the easy to spot gray mess, it sometimes creates the image with 4 sections with the lower right section maybe a stop darker. I missed this at first before uploading the files. If you look closely it is easy to see and destroys the integrity of the image
I love capture one, however this is a serious bug that undermines the program.
I am on windows 10, 32 gb ram, Dell xps 7590 2019 edition. Fully patched. I believe I am using the GPU support for the Nvidia graphics 1650?

Have you tried searching the forum for the strings "corrupt" or "corruption"?
You might like to - the likely answer's there.

Michael,
In the Preferences set the option to use Hardware Acceleration" to "None".
Then see if the problem persists.
If it does continue then the GPUs that may have been in use (or may not have been in use) are probably not the cause of the problem.
However, if the problem disappears then there is some sort of issue with the driver for either the Intel software GPU (if it is active) or the NVidia. You could try rolling the Nvidia driver back to a previous version and turning HW acceleration back on to see if the problem still appears.
If your Windows or Dell update history shows a GPU driver update that more or less coincides with the start of the problem it would be especially sensible to try this test.

Hey, you are not alone with corrupted exports. I have been experiencing them as well with latest version of capture one 21 ver 14.2.0.
In my case Capture one will NOT export to jpg or tiff correctly. It generates a scrambled file. The thumbnail seems to be ok, but the actual file is scrambled.
In my case, it only happens after I crop a photo, then apply a healing mask once or multiple times to the image.
To fix it, amazingly all I do close down Capture One and then open it back up again, and I am able to export successfully.
This bug is a MAJOR inconvenience.
Regards
Kevin

Hi,
Yes it is almost for sure the GPU driver (have not updated it for some time, outside of any automatic windows systems update). Turning it off within Capture One is not really an option (for performance reasons).
NVIDIA GeForce GTX 1650
Driver Date: 4/8/2021
Driver Ver: 27.21.14.6231 (windows) (I am using the one supplied in windows as approved by dell).
DELL XPS 7590 Latest patched windows 10, 32GB ram, iCore 7
And as Kevin mentioned above, restarting capture one fixes it.
If other programs, such as lightroom, photoshop, denoise, ... which make heavy use of the GPU , had the same behavior - then it could definitely be pinned on the GPU driver. It looks like memory is being overwritten, or allocated memory in a buffer is exceeded, or something to that effect. (32 gb of system ram, not sure how much dedicated ram in XPS laptop). In particular because some portions of the exported image are correct, and some (most) portions (handled in parallell) are scrambled noise.
As a programmer (with 4 decades of experience), i understand that these types of things can be difficult to find, however, highly suggest to expedite this to your windows team, to keep a close eye on it, and try to replicate it (before it compounds) (or if result of new code development). If it does turn out to be a driver version, then having this generate a warning will be a help to others (or a workaround for it). If not, well then another bug squashed.
I am willing to try the latest nvidea version of the driver, however, I have stayed with the stock approved dell one ( have not updated it for awhile), specifically because i need stability (and am not a gamer).
Thanks

It's not just Windows. I suddenly started having this issue on my OS X machine.
Restarting Capture 1 does NOT fix it and it is present in any size output of tiff or jpeg.
The previews are all just fine (and fine with hardware acceleration set to "auto")
Turning off Hardware acceleration for processing fixes the problems

I had the same problem exporting files from the recent updated Capture One 21 v14.3.0.85-- they were all badly corrupted as well as exporting at the wrong size.
I updated my Windows 10 desktop NVidia drivers and problem solved; I left my Capture One hardware acceleration in "preferences" both to "auto."

New Capture One user here, on Mac (Big Sur), and same problem for me. 2019 16" MacBook Pro with Radeon Pro 5500M and Intel UHD Graphics 630. Running Capture One 21 Pro 14.3.1.10 (latest version as of this writing).
The weird thing is that I went through a whole 30-day trial of the full Capture One software, spent some fairly extensive time with it, and had no issues. Then I used Capture One Express for a couple of weeks, no issues. Now, on the first set of photos that I've actually edited and exported with my newly purchased software, this happens.
I tried the various suggestions here, none of them worked except for turning off hardware acceleration for processing. Not at all ideal because it did take noticeably longer that way, and not much excuse for it on Mac where there aren't that many variations to support. Though at least that works, I guess – I was about to get very angry otherwise.
I'm still pretty unhappy about this after the amount of money that I just spent on this software. Capture One needs to get on fixing this issue.

I'm having the same issues on my Mac. Thumbnail looks fine but when i open the jpgs they are a completely mess. Not happy about it at all, especially when you're paying £16 per month! Capture One needs to get a grip and sort it out. Seriously considering Lightroom classic now for just £10 a month.
Turned off the hardware accelaration and it seems to have worked but still I shouldn't be turning things off to make Capture One work properly! Unbelivable!

Same problem. I'm using the current, standard windows drivers for my laptop nvidia graphics card (MX250). I'm currently testing Capture One. I'm not going to switch to C1 unless I can solve this issue.

This program is not cheap. We are offered a new version without repairing the old one. I've lost a lot of time and money and there is still a post-work with export that prevents professional work.
