[comorbidity]

Howdy!

I recently upgraded my main workstation to Fedora 41 and tried to fire up eduke32 for the first time.

After pulling r10608-8d79c372a from the git repo, I cleaned and built a new binary. Compilation went fine (some warnings).

Firing it up resulted in a segfault:

So I tried setting a few different environment variables to see how far down the line I get.

GDK_BACKEND=x11 -- the eduke32 configuration dialog will display just fine, but the SDL viewport / window doesn't appear on screen. Game runs in background.

SDL_VIDEODRIVER=x11 -- eduke32 config dialog appears, SDL viewport is displayed. Framerate is slightly choppy depending on scene complexity.

SDL_VIDEODRIVER=x11 ./eduke32

eduke32 will happily run in gamescope, albiet with major performance dings and visual artefacts.

....and surprisingly, the Ion Fury binary from Steam runs just fine with system libraries!
