rgb curve strange behavior(?)

Software darktable

I restarted DT before recording. Please watch and tell me what you think.

DT 5.5.0-338, self compiled, Ubuntu 24.04.4. gcc 13.3.0
I always do a clean build (I delete everything before building and installing).

I get similar strange stuff with current master from obs.

So it’s probably worth an issue on github.

Could not reproduce with self-built DT on Fedora 43. Played around with rgb curve following GitHub steps and the video - no issues found.
