in Ubuntu 20.04; if my mouse is grabbed by a vm and I try to take a
screenshot via "Screenshot" - default snipping tool in "Select area to
grab" mode-, as I click the "Take Screenshot" button, my mouse icon
switches to snip mode but then mode selection window reappears as
pressed "ESC" button. In my experience, this behavior appears if your
mouse drops to a vm which had already grabbed your mouse.

if you move your mouse to the top bar or side bar, your mouse icon
switches to snip mode but it is false positive since when you click it
just does not function. And if you click "Take Screenshot" button again,
even you successfully take a snap, your click function that brings
windows forward, disappears. So, lets say if I use double monitor and
each has a window on the front. If I click other window to interact etc,
it wont do any good. I can not get my keyboard and mouse in the focus of
another window. Also at this point, I can not use top right bar features
as well.

What I can do is, use ALT+TAB to switch windows. And by this was, I can
switch the focus and interact with my mouse and keyboard.


I might remember wrong but this was not happening in 18.04.

I hope this is fixed soon cuz I really get myself into this trap often,
especially if I use double vm which I control each on different
monitors. I must remember to use "CTRL+ALT" combo to let loose my mouse
from vm's.

This is the second VM related issue which I got this year.

Title:
  gnome-shell randomly blocks mouse clicks from working in app windows

Status in GNOME Shell:

Bug description:
  Under GNOME 3, the use of the mouse-click stops occasionally, though I
  can still move the mouse around and can still click on items in the
  Activities screen and the top-bar.

  I can use alt-tab to cycle windows and can still type into already-
  active textboxes in windows, but I cannot click within the windows,
  and the mouse is not picked up at all by the windows.

  I can open the alt-f2 "run command" dialogue, but cannot type into it.

  The workaround I'm using is to open terminal (ctrl-alt-T) and run
  "gnome-shell -r", and restarting that command every time I have the
  problem again.

  Please ask if there's anything I forgot to mention.

  ADDITIONAL: The error tends to happen randomly, but it seems to happen
  upon opening a new window, changing windows, closing windows, or
  opening the activities pane (whether a change of window is thus
  instigated or not)

  ADDITIONAL 2: (sorry, it's early) The other workaround is to log out
  and to log in again, but that is also less than ideal
