věřím,že už dávno paříte, ale kdyby náhodou..
However, I decided to try disabling gameoverlayrenderer in the "libraries" tab
of winecfg, and that works too.
(If you don't know how to do this, go to the libraries tab, type in
"gameoverlayrenderer" without quotes in the new override box, click add, then
highlight the new entry, click edit, and then select "disable".
