Glitching graphics with AMD GPUs and the amdgpu module

There may be problems due to differences in memory models in userspace and kernel drivers, in particular with 64-bit OpenGL applications running with AMD GPUs that use the amdgpu kernel module.

Either enable FELIX86_ENABLED_THUNKS=glx, or if running into issues with that, enable TSO with FELIX86_ALWAYS_TSO=1.
