Bug#1128816: gnome-shell: Slow/broken animations since updating to 49.3

[Paul Menzel]

Package: gnome-shell
Version: 49.4-1
Severity: normal
Upstream: https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/8992

Dear Debian folks,


Now idea if *gnome-shell* is the right package.

This is an Intel Kaby Lake laptop Dell XPS Debian with sid/unstable.

     00:02.0 VGA compatible controller [0300]: Intel Corporation Kaby 
Lake-U GT2 [HD Graphics 620] [8086:5916] (rev 02)

I am not sure, but I think since upgrading to 49.3, switching workspace 
and even windows sometimes takes up to ten seconds. Shortcuts like 
pasting with Ctrl + v also lags, when it happens.

There are two upstream reports [1][2], where the second one is mine, 
though it looks like a duplicate.

Unfortunately, I have no idea how to debug this. There is nothing in the 
logs.


Kind regards,

Paul
