        <pre>With the game Quake Champions running using Steam Play 3.16-4 and 3.16-5 Beta
there are significant problems on loading screens: many elements of the screen
are blinking constantly.

A video showing the loading problem can be seen at:
<a href="https://cdn.discordapp.com/attachments/457747189616214019/524176774192693249/quackchampions001.webm">https://cdn.discordapp.com/attachments/457747189616214019/524176774192693249/quackchampions001.webm</a>

After joining a match (which takes a significant time), all textures may
disappear for a brief time and reappear. This can be seen at:

In the DXVK logs (QuakeChampions_d3d11.log), the following error can be found
(I copied from the log):

err:   D3D11: CreateGeometryShaderWithStreamOutput:
  Transform feedback not supoorted by device

Which seems a bit strange as I remember there were commits about adding
Transform Feedback around 2 months ago and Quake Champions still do not detect
it.

I'm reporting this problem here as it was asked at:
