Any time I try to save an image, it saves as a white box

This is driving me nuts. I do a minor edit to one of my RAW images, select save to export the image and every time, it saves it as a white box.

Has anyone seen this glitch? It is making RawTherapee unusable.

Thank you in advance for the help.

What version? What computer? What operating system? What type of raw file? Can you post one that won’t save on your system … and it’s .pp3 file?

Could help someone here who knows more than me … all I can say is that mine works which is no help to you at all.

Version 5.10, home built Rysen 7 running Linux Mint 22.

The raw files are out of a Canon EOS 7D. I haven’t had this issue in the past up until about 2 months ago when the problem started to happen. I thought it was just a bug so I waited for a few updates to RawTherapee and it still happens.

Post a sample picture so others can test. The pp3 might help as well. Without a sample image people might be struggling to help. Also ART is a fork of RT, I wonder if that might work better on your system?

From Wikipedia:

If a raw format is not supported it will either not open, or the preview in the Editor tab will appear black, white, or have a strong color cast - usually magenta.

From what I understand, you can open your raw and it looks good, so your raw format is supported. Then we need to know, as Ted pointed out, what you are doing next. A pp3 would help.

Have the same issue since upgrading to 5.11 (flatpack). Happens randomly while saving an image. Running on Pop OS 22.04 LTS. Work around: save the image a second time. Very annoying indeed.

@Ghostwug How often does it happen? I tried saving an image with your pp3 10 times and it worked correctly every time.

As I stated earlier it happens randomly, I guess six times in a hundred. The pp3 is not the problem as you can save the file again without the boxes. It happens during saving. I now save through the queue and so far no problems.

It’s still possible that something is happening during the processing step, or that the issue only manifests when the image has certain qualities. Using the same pp3 improves reproducibility. I tried a couple more times and still did not see the issue. Maybe I got unlucky or there is something special about your images, OS, or hardware.
