"...  Cinnamon will freeze everything up for about 10 to 30 seconds. Sometimes
it also takes over two minutes and I decide to kill it from Ctrl+Alt+F1.
Sometimes it unlocks from that terminal (with the help of DISPLAY=:0 cinnamon
--replace), sometimes I have to restart the session and loose any unsaved work.
While frozen, the clock does not update, I cannot use alt+tab, I cannot open
the start menu, I cannot click anything, I basically can't do anything besides
moving my cursor around. The windows will also not update: if someone says
something in a chat, I won't see it until it unfreezes. However music keeps
playing, networking is uninterrupted and everything in ctrl+alt+f1 works fine.

While frozen, if I run top/htop/iotop in the ctrl+alt+f1 terminal, there is
nothing unusual to see. Little cpu load, ssd is mostly idle, RAM is far from
full, and I don't use swap. There doesn't seem to be anything odd in dmesg.

I haven't been able to find steps to reproduce the issue. The frequency seems
to increase when I do a lot of alttabbing or when Libreoffice is open, but I
really can't say that with any certainty."
