Gzdoom black textures

[Marlamir]

I don't know why, but getting this strange bug(?) in gzdoom. The problem is black textures and floor.

 

I don't know why is this happening. This sector and lines has no action,script or anything that changes brightness. The only thing this sectors have is set_color script but other sector with same tag have no problem with black textures. I tried to play with settings as much as i can and nothing. Fake contrast is turned off btw. Textures used was stock compblue. Im noob who doesnt know how to fix it any help?

 

Edit: Textures are well visible in gzdoom builder
