Comment 8 for bug 63245

Though this bug report is quite old already I still hope there can be a fix sometime.

This bug is associated with metacitiy, but it affects KWin and any other window manager that I know and tried some time ago as well, so I assume that the place to fix it might be Xorg, rather than the window manager, but in the second case I'd hope for a solution for Kwin as well.
