[amdgpu] Opengl or vulkan or mesa bug that causes textures to glitch when mipmapping or trilinear/bilinear filtering is enabled

[AS]

Textures are glitched (almost like they are cut up and repeated) when mipmapping or trilinear/bilinear filtering is enabled. Workaround is to disable both.

I believe it is related to this mesa issue, though the type of corruption is different,(https://gitlab.freedesktop.org/mesa/mesa/-/issues/1399) because running with AMD_DEBUG=nodma resolves the corruption.

I meant amdgpu not mesa.
