When entering a world and playing for a couple minutes, the game window starts flickering with blue every other frame, if you play during that time and wait, the display freezes between 2 frames alternating.

All the time from entering the world, the game produces log like this:

[22:03:08 INFO]: Client> [22:03:08] [Client thread/ERROR]: ########## GL ERROR ##########
[22:03:08 INFO]: Client> [22:03:08] [Client thread/ERROR]: @ Post render
