Today's update to gnome-shell 3.36.0-2ubuntu2 seems to have fixed this for me.

After upgrading various GNOME components to version 3.36.0-2ubuntu1 I'm seeing the following with several applications open of four desktops: 1) 'Alt-F2 r <enter>' restarts GNOME Shell but displays an image of all currently running applications on the current desktop. Moving to another desktop corrects the problem. Similar to bug 1819890 which was closed as fixed for this release. 2) With Thunderbird running on 'Workspace 2', any attempt to open a menu produces an image of applications running on other desktops underneath Thunderbird. 3) Above also applies when using Libreoffice and HomeBank so probably applies to any application that displays a menubar. I'm unsure of which package to report this against so reporting against mutter and adding gnome-shell.
