Summary: Mouse input causes major performance loss Product: Wine Version: 1.3.28 Platform: x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: pastas4@gmail.com
Since I upgraded from Wine 1.3.26 to 1.3.28, I have noticed a regression in all games I have installed on Wine - their performance is a lot lower and in some of them graphical glitches appear.
The performance regression is clearly due to the input. For example, if I don't move the cursor, everything works fine - the performance is what it was earlier and there are no glitches, but as soon as I move the mouse, the performance is lowered dramatically (to around 1 FPS in every game I tested) and in some cases, such as running Heroes of Might and Magic III in a virtual desktop, graphical glitches appear (a box around the cursor that displays incorrect data - from another part of the screen).
