Description Michael 2019-04-15 08:42:27 UTC

Certain applications (eg. most Minecraft shaders, Substance Painter, and probably a bunch of other games) tend to assume that GL_EXT_gpu_shader4 is supported everywhere. This makes Mesa (and particularly AMDGPU) users sad, as shaders won't work, instead filling logs with messages like "warning: extension `GL_EXT_gpu_shader4' unsupported in fragment shader" and "error: no function with name 'texelFetch2D'".

(Hopefully I tagged the right component...)
