Flickering on steam deck

[JustinRodri3000]

When trying to use it on the steam deck using either bottles or forcing compatibility with proton, the screen turns black but a small section over the logo. Then when I move the mouse the screen quickly flickers showing program and then back to black. The program is still usable just it is very difficult to see what I am doing.

Happens when you run Unverum through DXVK.
Launch it with PROTON_USE_WINED3D=1 for Proton or WINEDLLOVERRIDES="dxgi=b;d3d9=b;d3d10core=b;d3d11=b" for Wine.
