high cpu usage with no activity

[smurphos]

what does W+L do and how do you do it?

It's Windows Key (aka Super key) + L shortcut to open the Cinnamon Debugger GUI application aka Looking Glass aka Melange. There are easier shortcuts to restart Cinnamon.

Ctrl-Alt-Esc is one.

Another is Alt-F2 to bring up the run dialog and then type r and press enter.

Right Click on the panel, click troubleshoot and then click restart cinnamon is another way.

I am experiencing high cpu usage in the 60-80% range on all 8 threads with no activity.
cinnamon --replace is doing this.
I have seen this issue before and I have tried everything that worked before, but nothing works.
I removed all applets. I had some bad applets before.
I tried a desktop reset with alt+ctrl+esc.

Anyone else seeing this?

I upgraded from mint 19 beta to mint 19 full and this started happening.

Maybe you won't believe, but I uninstalled the Bluetooth process that checks all the time for new devices and, suddenly, all worked fluently.
