Workaround for a bug in QClipboard that occurs when the clipboard has been used within the app and its content exceeds a certain size on X11/XCB. This issue will hold up the app when exiting and is present in Qt5 versions. With this workaround, the content of the clipboard will be lost when exiting, but the app will exit normally.
