Bug Description
SRU
[Impact]
This bug is quite disruptive, in fact, if this extension is installed and active, it renders gnome-shell almost unusable. Anytime you open gnome-shell's overview (using the super/win-key) or you just press on the "Show Applications" button on the panel, instead of opening the overlay correctly something weird happens and you cannot close it back in any way. The only workaround I found is to press Alt+F2 and press R to restart the shell (using Xorg).
This package used to work until a recent gnome-shell update to 3.36.5 as part of 20.04.1, which changed some API related to setting geometries (https:/
This package is clearly broken in its current status, so I suggest backporting the latest version from groovy (38-2), which has an update that fixes the issue. I'm using it for three days now and it works perfectly like it used to do before this bug arose.
The fix is likely this one-liner https:/
[Test Case]
What happens?
1. Install this package, and enable it (e.g. from the Extensions app) if it's not already enabled upon install.
2. With this extension enabled, try to open the overview (e.g. by pressing the super button).
3. The overview appears corrupted, from now on it's no longer possible to close it and the windows are stuck in their position.
A screencast of the bug is available in comment #2 https:/
What should happen instead?
At step 3 the overview to work normally and be able to switch applications as usual
[Regression Potential]
As the bug the current version is very disruptive, breaking entirely the use of the shell, the risk of regression is extremely low. It may introduce instabilities to gnome-shell which have not been discovered yet. I'm personally using the groovy 38-2 version for 3 days on my main device and I didn't detect any problematic behaviour.
[Other Info]
An alternative could be to cherry-pick the single fixing commit, but I did not test it, nor have been tested by upstream, hence I suggest to directly backport version 38-2 from groovy.
--- Original Description ---
Since the last boot, few minutes ago, anytime I open the gnome-shell's overview (using the super/win-key) or I just press on the "Show Applications" button on the panel, instead of opening the overlay correctly something weird happens and I cannot close it back in any way. The only workaround I found is to press Alt+F2 and press R to restart the shell (using Xorg).
If I disable the extension, everything works correctly, so I think it to be culprit.
What happens when I try to get the overlay and it gets stuck? You can see the attached screenshot. Note the name of the window on the top right, it appears as soon as I trigger the overview, like if the overlay was open but the window was not getting resized. If I try to drag the window, an animation shows like if the overview was correctly working, but nothing works.

I'm posting a screencast of the issue, as it may be more clear what the issue is.
At 0:22 I click Show Applications, around 0:38 I use keyboard shortcuts to move back and forth between the first and second virtual desktop.
