Huh this is going to be tricky to figure out. I explicitly avoided hard-coding the libGL dependency in mangohud because games should already have libGL or vulkan loaded to render the game... I don't think it's a good idea to force the wrapped game to use a version that could be incompatible.

But from what I'm seeing with minetest, it looks like it uses libGL indirectly through IrrlichtMt, and won't have it loaded at the time mangohud hooks into the game.

It seems like mangohud does work if I hardcode libGL, but the font rasterization seems a bit off, and I want to make sure that adding it won't break other games:
