SUMMARY If Night color is enabled and you go to System Settings -> Display and Monitor -> Gamma, it is abruptly disabled. This is fine although it could be improved by a smoother transition, like when it's properly enabled and disabled by the user, the problem is that after exiting the Gamma menu, Night color is not enabled again. The solution is to disable and enable manually again. STEPS TO REPRODUCE 1. Enable night color 2. Go to Gamma settings OBSERVED RESULT Night color suddenly disabled, and not restored after exiting Gamma menu. EXPECTED RESULT Night color is disabled with a smooth transition, and enabled back again when exiting Gamma menu.
