These happen at least with the QEmu and Intel GPUs (HD Graphics 4600). Because
these warnings appear in the Wine log they cannot be seen in the nightly
WineTest reports. However one can see these warnings in the TestBot's Debina
WineTest jobs, both in the summary and in the "task.log" files.

Also, to see these warnings one has to delete the shader cache since they
happen during compilation:

  rm -rf ~/.cache/mesa_shader_cache/

Commenting out the tests shows that these warnings are caused by the following
d3d11 tests:
  test_sample_shading()
  test_standard_pattern()
