OpenGL suddenly not working

[RikkHarrison]

A few days ago, I had installed and had been playing GZDoom. But today, when I tried to run the game with OpenGL, fraps said it was running at 0 fps when it opened. I tried running the Dolphin emulator in OpenGL as well, and it had the same problem. I tried updating my drivers, but that didn't help. I using an Intel Celeron 1037U with Intel HD Graphics.

im assuming your on linux

try to manually restart service connected to opengl or the display driver

check your updates history and see if anything installed

try repairing the gzdoom itself (apt-get "package name")
