description |
When using *some* applications (I observed it with Emacs and gnome-terminal) in full-screen mode, they flicker once shortly after switching to them with e.g. Alt-Tab. To reproduce it:
1. Open Emacs in full-screen mode and one other application (e.g. Chromium).
2. Switch to the other app with Alt-Tab.
3. Switch back to Emacs.
Then I observe:
1. Emacs becomes visible.
2. After a fraction of a second, the Emacs windows is transparent for a very very short time (flicker).
3. Then, the windows is stable and usable.
Usually, I do not observe this behaviour right from the start. I have to work with the computer for a couple of minutes to see it. I have been unable to find out whether a certain action triggers the problem. However, when it occurs, it does not go away again until the next restart of the X server.
This is regression that I observe since Ubuntu 19.10.
Changes of the graphics driver does not change anything, however, switching to Wayland solves the problem. |
