Summary: games using full screen mode leave "dirt" on desktop Product: Wine Version: 0.9.14. Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: wine-directx AssignedTo: wine-bugs@winehq.org ReportedBy: lothalev@gmail.com
Games running fullscreen (probably only using resolution lower than desktop resolution) leave cyan-black background on exit (the same as wine's virtual desktop). The screen has to be manually refresh to fix it.
Using KDE 2.5.2, Xorg (happening both in 6.8 and 7) with Intel 852/855GM chipset, DRI.
It didn't happen before about 0.9.10 version of wine, neither happens with any other application.
