Fedora has just upgraded from Wine 3.19-staging to 3.20-staging, and now the
textures in World of Warcraft (D3D11) are corrupt. This corruption is mainly
visible in outside regions, but within a radius around my avatar. There are
also flashes and slices of primary red/green/blue in the dark regions which
seem to occur randomly.

Screen controls, such as a menus, action bars and maps/mini-maps are
unaffected.

My graphics card is AMD R7 360, and Linux 4.19.4 kernel with amdgpu driver.

Mesa reports itself as:
