Comment 36 for bug 1734095

This is still a problem and has been driving me nuts over the last month or so. I'm probably motivated enough to try and retrieve more information out of this (to help debug this) in case someone could point to me how.

------------------------------------------------------------------------------
MY THOUGHTS:

If I'd have to wager a guess..:

-> I'd say the bug exists in something related to Window Manager
(in case that's responsible for managing window focus)

-> It's probably not gnome-shell related
.. because I'm running Cinnamon

-> It's common to GNOME Desktop Environment and Cinnamon Desktop Environment, because the bug has been reported here
.. and since the bug was reported over 4 years ago, it's probably something that's not changed in all this time AND is shared code between these two projects.

------------------------------------------------------------------------------
THE BUG:

Occasionally mouse clicks stop being sent to the window that's active. They either seem to be lost/ignored, or are sent to the wrong window (which I observed by selecting text in a terminal and text was instead being selected in another terminal window).

Keyboard works correctly, and can change window focus by Alt+Tab.

------------------------------------------------------------------------------
WHAT I TRIED:

Running `cinnamon --replace & disown` and it didn't help. The only result was, that I was given some output, such as multiple lines of:
> Cjs-Message: 12:17:06.726: JS LOG: pushModal: invocation of begin_modal failed
and
> (cinnamon:50760): Cjs-WARNING **: 12:27:40.742: JS ERROR: TypeError: b is null
Panel.prototype._updatePanelVisibility@/usr/share/cinnamon/js/ui/panel.js:3481:44

The stupidest thing is, that after playing around without mouse for a while, the problem disappeared by itself! (about 5 to 10 minutes)
