As shown in the images below, even after termination, DT continues to consume (and heavily) CPU resources.
Furthermore, in the light table, some photos do not load correctly:
Can anyone help me with this? Thank you.
Do you use OpenCL with a very old / weak GPU, especially with a CPU’s embedded GPU? If yes, you may consider turning it off in preferences.
Without further context, it’s guesswork. Can you describe your machine? Operating system (Linux, Windows, Mac), CPU, GPU, memory?
I see you use a development version of darktable; I assume it’s a recent one, is that correct?
It almost sounds like DT is playing catchup to create and sync thumbnails but I have no idea if this can happen outside of when DT is actually running. I thought this was a background task… Have you been playing with any scripts recently ?? I wonder if that could be running some commandline stuff that is working or hung up?? Sorry I have not experience with this happening ever while I used DT

You haven’t answered the question around the version of dt. Zooming in, it looks like a development version. What’s the source? Install this one: darktable windows insider program 10/26/2025
What’s the version of your GPU drivers?
After you use the version above, if the issue is still there, provide the Logfile from -d common.

It’s a build from about 2 weeks before:
Maybe you should disable the embedded GPU in the BIOS, and use the discrete GPU only.
