And that’s the big advantage of a (good) open source project compared to most commercial software: devs are more responsive, “easy” bugs can be fixed quickly and you can get the fixed version immediately (with a bit of work and knowledge on your part, still).
Thank you very much, @hannoschwalm
Just curious, how’s the debugging so far?
TIA
The fix is already in master
Great, so what I need to do now? to re-install DT?
You can either wait for an official bugfix release (I’m not sure we’ll have one), or until the next big release, 5.4 (released at Christmas, usually), or use one of the nightly / weekly builds.
The nightly builds are here: Release Darktable nightly build 20250917 · darktable-org/darktable · GitHub
Weekly builds are provided by @wpferguson , see his ‘windows insider’ posts. The latest is darktable windows insider program 9/14/25. [Edit: by the time I updated my post, @123sg already posted the link to Bill’s builds.]
There’s no need to uninstall darktable. You can either install the nightly in its place (back up your config and database, otherwise you won’t be able to go back in case something breaks), or install the nightly to a separate directory, and adjust settings to use a separate configuration directory (see --configdir at darktable user manual - darktable). I always use the latest build as my daily driver, and hardly ever run into problems, but YMMV.
@LimCW , this is the most recent weekly Windows build but there should be another next week. 
(to state the obvious!)
OK, thank you so much.
Thank you so much.
