Hello @rogowskys, we're using one issue report per unofficially supported game title, so I've gone ahead and transferred this issue report to https://github.com/ValveSoftware/Proton/issues/333#issuecomment-628210049.

After the latest World of Warships update - 0.9.4 - the GUI is missing items and in places corrupt (see images). Specifically the Top Bar, Modules and "Tech Tree"

The following was tried, with NO EFFECT:
Proton 5.0-7 (default) and Proton 4.11
Mesa 20.0.6 and 20.2 git ( to rule out RADV or radeonsi)
Fedora kernel 5.6.11 and xxmitsu 5.6.0-amdgpu-next (to rule out amdgpu)
PROTON_USE_WINED3D=1 ( to rule out DXVK)
Local steam files were verified - ok. I verified that the game loads and displays the GUI just fine using Steam on Windows. Previous WoWs versions 0.9.3 also exhibited random crashes that I could not track down.
