XnView Software

XnViewMP 1.4.4 64bit
Windows11 (22H2), display resolution 3840x2160, win scaling 150%

Enhanced colors dialog
improve scales UI

Suggestion
A
align start of RGB scales with the scales above

B
scales are from -100 to 100, so why major tick marks are different?
they shall be the same

C
when dilog stretched a bit - minor tick marks appear on 3 scales only
guess it is better to disable them for all scales

Thanks to your detailed description I can reproduce the problem.

This problem is supposed to be fixed in XnView MP 1.4.5. Please check and confirm the bug fix here.

fixed in 1.4.5
