Hangs during startup on linux if video mode is changed to OpenGL

[Michael Ablassmeier]

hi,

after changing video mode from default to OpenGL in the game menu it works.
After restarting the game it wont come up, either gzdoom runs out of memory (killed via OOM by the kernel) or simply "hangs" during load screen.

I figured that removing

$HOME/.config/gzoom/cache

solves this problem

Is this a general GZDoom bug?
