Sometimes certain notifications make the desktop unresponsive for a few seconds and then gnome-shell crashes and all extensions are reloaded.

I have found an upstream bug with a patch, but it's probably not in the Ubuntu's package. I thought of creating an issue in case it is something not known.

In my case it happens only with the notifications of gsconnect and maybe android studio.
I have reproduced the problem in gsconnect in case it helps.

the error is:
lug 27 19:55:56 ghv gnome-shell[4071]: Object Meta.Background (0x55ce6b4cf300), has been already deallocated - impossible to access it. This might be caused by the object having been destroyed from C code using something such as destroy(), dispose(), or remove() vfuncs
