--- Comment #4 from Thomas Lübking <thomas.luebk...@gmail.com> --- The compositor settings won't matter - it's most likely a known problem in Qt. Try to suspend the compositor (SHIFT+Alt+F12), run glxgears and move a drag over the running glxgears window. See what happens. -- You are receiving this mail because: You are watching all bug changes.
