After upgrading my VPN from 20.04 to 22,04, I at times get the following desktop and clicks on it do not work. Any idea how to fix it?

Here is a screenshot of what I get: enter image description here

I tried rebooting (warm and cold boots) and quite often I get the same result. What could create this issue? Would there be ways to fix it?

My take is that it completely misinterpret the 200% setting (which I need because I have 4K monitor and everything is too small without it).

Oh and I can't run anything because clicking on windows / resizing doesn't work. As if the desktop was totally preventing such from happening. Really weird state.

Another thing, I have 4 screens and when I go to another one with Cmd-F1, Cmd-F2, etc. I actually see the full desktop as expected for a split second.

I found one solution. It's not ideal, but at least it keeps me going.

I think that the issue is that the desktop area uses the "old" (default) resolution of 800x600 because somehow it's not able to use the correct resolution in the login screen after a reboot.

Killing the gnome shell and login back in saved the day for me:

sudo killall -QUIT gnome-shell

In my case, after that command, the login screen came back with the correct resolution.

Since in that situation I can't really do anything on my screen, there is no need to warn you to save your data before running that command. However, if your situation is different, that's your warning. It is likely to kill all your user's processes whether you saved your data or not.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
