What changed in rendering between 4.10 and 4.11 versions?

[neoworm]

EDIT: What changed is that "legacy" sector light modes were removed from options and need to be switched to via console and won't stay after closing GZDooM. You can use autoxec method to override it though.

Apart from having no idea why was default settings changed, what even changed? I tried to comb through changelogs and options but I wasn't able to get the look from 4.10 on newer version at all.


Main problem is this:

This was pitch black sector in 4.10, but it now is fully visible plus the player's glow makes really weird and really ugly ertifacts on the sector gradient.
