If so, op‘s window manager would be KDE. Let‘s see what he reports.
No; that problem has also been reported on LXDE and XFCE. The workaround described in bug 30587 is KDE-specific, but the problem is not.
A quick test would be to uncheck the "Allow the window manager to control the windows" checkbox in winecfg. If that fixes it, it's probably the same bug.
