    Description

      Run any Quick app with text elements on D3D12. The glyphs look fine on NVIDIA but have artifacts here and there (styled and outline mainly) on AMD.

      Affects R8 glyphs only. Converting these 8-bit ones to 32-bit and switching .r to .a makes it work so it is something with DXGI_FORMAT_R8_UNORM.
