Source engine toGL games crash when not using x11

[fxesminus]

Distro: Arch Linux
Happens both on SDL2 and sdl2-compat.
Both kmsdrm and wayland make the program crash.
As far as i can tell the games don't use any xlib quirks, also i remember it working using the offscreen backend but now it doesn't anymore.

Can you provide a stack trace, ideally with a debug version of SDL?

I can't manage to do a stacktrace but it might have to do with the fact that the game seems to load libGL and GLX using dlopen rather than being in the elf header
