You have been subscribed to a public bug: 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. ** Affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Tags: bot-comment -- Full-screen window flickers once when switching to it https://bugs.launchpad.net/bugs/1861391 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
