I am "testing" with mass effect 1 in a 1920x1080 wine virtual desktop.
The trouble is mainly with minimizing and restoring windows.
OpenGL/GLX Compositing (kwin): I have still this issue

title="REOPENED --- - prime: black window"
href="show_bug.cgi?id=69101">https://bugs.freedesktop.org/show_bug.cgi?id=69101</a>
So on the first start of the game the graphical output is (almost?) always
stuck at the splash screen and I have to press the ctrl+alt+f12 hotkey to
disable and re-enable compositing. When minimizing and restoring the window it
has about 2/3 chance or so that it will not render and I have to minimize or
disable/re-enable etc.
Xrender Compositing with both compton --backend xrender and kwin:
The above problem with not rendering does not happen with xrender compositing.
Instead: When minimizing the wine window, the game will render over everything
on all workspaces while minimized.
I can provoke a graphical output hang when:
1. Use kwin with opengl compositing.
2. Minimize and restore until it hangs.
3. While it hangs, switch to compton --xrender.
Then the graphical output and does *not* recover with disabling/reenabling
compositing or minimizing/restoring multiple times, I have to kill it...
The game itself doesn't hang, I can hear the results of input etc. It's just
the graphical output.
I have no idea how to try to debug this, but I will see if it is possible for
me to find out more about why this happens.</pre>
