Restarting gnome-shell displays images of applications running on other workspaces
Restarting gnome-shell (3.32) with 'Alt-F2,r and enter' displays images of applications running on other workspaces which are not clickable.
Steps to reproduce:
- Enable multiple workspaces
- Start an application on each workspace
- From any workspace, restart gnome-shell with 'Alt-F2, r and enter'
Each application is displayed only the workspace on which it was started.
All applications are displayed on the current workspace. The applications running on other workspaces are displayed as images, i.e. they cannot be 'clicked' but the 'wanted' application, the dock, top bar etc all function correctly.
To remove the unwanted images move to another workspace and then return.
