Since there is no specified thread for bug reporting I'll leave this just here.
I observed that objects may (partly) lose their opacity and/or begin flickering when the player is touching a wall.
When I move 1cm away from that wall everything's just fine.
As you see below. First image is standing against a wall, second image is stand 1cm off a wall.
FYI it's nothing that bothers me too much I just wanted developers or experienced users to know.
