I see no Video output. The mouse cursor changes to a different than the Cinnamon-Cursor and I can move it only in the top left corner of my desktop.
The Sound for the Startmenu works though.
Start the Game.
Ryse Son of Rome works perfect with Proton 4.2-2. That fullscreen issue seems gone.
I'm still having the same Issues with Proton 4.2-2
I found 3 different bugs in this game.
First one is the same as topic starter described. It's still persist in Proton 4.2-3, but can be easily avoided by alt+tabbing to Steam window and alt+tabbing back to the game.
Second issue is with alt+tabbing from game - after you alt+tabbed you can't use your mouse and mouse cursor is the same as in the game.
Third issue is with some shadow flickering. It occurs only in few parts of the game and almost always in the night. I attached 2 screenshots from the same place to demonstrate the problem. Problem persist in both DXVK and WINED3D.
