Dear Maintainer, *** Reporter, please consider answering these questions, where appropriate *** * What led up to the situation? I use mwm on my system (X11 with nouveau). If I suspend the system via "systemctl suspend", sometimes the situation occurs that after I woke it up, I can't use the mouse on mwm, but on the active X clients. Keyboard shortcuts work properly (like Alt+Tab), but I cannot use the context menu on the window borders nor the background. It happened many times, but not every time I sent the system to suspend. If you need more information, please tell me, so I can provide it.
