In Darktable, I have bound some basic sliders to key + mouse wheel shortcuts. For example, I have bound F1+scroll to exposure.
Now, from time to time (very roughly every 30 or so launches) the program forgets these key + scroll shortcuts, but curiously only those. Other shortcuts (like double press F1 to reset exposure) remain in place.
I have not been able to narrow down when this occurs. It just so happens that from time to time after firing up Darktable I notice that F1+scroll does not work. Then I have to quit the program and restore shortcutsrc from a backup.
This happens with Darktable 5.0 on Debian, but previously I saw the same behavior with Darktable 4.6 (both from a Debian package and self-compiled). I could try out 5.2, but unless this problem has been addressed specifically, I don’t think that the chances are good that it is no longer present.
Has anyone ever observed something similar? Any suggestions how to debug this?
