The bug is similar in appearance to bug #57189 but it is caused by a different
commit and is not fixed unlike 57189.
The game screen is distorted and doesn't fill the screen properly.
Occurs both in fullscreen and virtual desktop mode.

The commit causing the problem:
commit 4c15acf234a575b7b054016e2a0099202885d87f
winex11: Detach offscreen OpenGL windows after creation.

Plain terminal output doesn't show anything relevant.
You can reproduce the bug in the Steam version or with the original demo
version released in 1997:
