I am running a notebook (AMD-Ryzen9 with a nvidia-accelerator). The Alt-DP is driven by the nvidia hardware and it uses an USB3.2 port. This configuration is commonly uses for AMD notebook. I am running a Gnome-Desktop on Wayland. From time to time, the attached display is getting dark for less than a second and comes back again. Journal gives no mutter oder nvidia related error messages, but i get this weired output: Aug 11 14:01:37 foreman gnome-shell[6127]: #5 557cf848fd68 i resource:///org/gnome/shell/ui/layout.js:366 (b4b963cc6f0 @ 22) Aug 11 14:01:37 foreman gnome-shell[6127]: #6 557cf848fcd8 i resource:///org/gnome/shell/ui/overview.js:642 (1cf1f9982830 @ 175) Aug 11 14:01:37 foreman gnome-shell[6127]: #7 557cf848fc58 i resource:///org/gnome/shell/ui/overview.js:625 (1cf1f99827e0 @ 12) Aug 11 14:01:37 foreman gnome-shell[6127]: #8 557cf848fbd8 i resource:///org/gnome/shell/ui/overviewControls.js:771 (1cf1f9985c40 @ 55) Aug 11 14:01:37 foreman gnome-shell[6127]: #9 7ffd017d55b0 b resource:///org/gnome/shell/ui/environment.js:151 (b4b9637c4c0 @ 39) Aug 11 14:01:37 foreman gnome-shell[6127]: #10 7ffd017d5670 b resource:///org/gnome/shell/ui/environment.js:317 (b4b9637c9c0 @ 14) Aug 11 14:01:37 foreman gnome-shell[6127]: == Stack trace for context 0x557cf0c9f130 == Aug 11 14:01:37 foreman gnome-shell[6127]: #0 7ffd017ce5b0 b resource:///org/gnome/shell/ui/workspacesView.js:692 (790ad827060 @ 591) Aug 11 14:01:37 foreman gnome-shell[6127]: #1 557cf848ffa0 i resource:///org/gnome/shell/ui/workspace.js:854 (1cf1f99bb5b0 @ 369) Aug 11 14:01:37 foreman gnome-shell[6127]: #2 557cf848ff18 i resource:///org/gnome/shell/ui/workspace.js:805 (1cf1f99bb510 @ 17) Aug 11 14:01:37 foreman gnome-shell[6127]: #3 557cf848fe80 i resource:///org/gnome/shell/ui/workspacesView.js:1007 (790ad827a10 @ 124) Aug 11 14:01:37 foreman gnome-shell[6127]: #4 557cf848fdf0 i resource:///org/gnome/shell/ui/overviewControls.js:720 (1cf1f9985a10 @ 50) Aug 11 14:01:37 foreman gnome-shell[6127]: #5 557cf848fd68 i resource:///org/gnome/shell/ui/layout.js:366 (b4b963cc6f0 @ 22) Aug 11 14:01:37 foreman gnome-shell[6127]: #6 557cf848fcd8 i resource:///org/gnome/shell/ui/overview.js:642 (1cf1f9982830 @ 175) Aug 11 14:01:37 foreman gnome-shell[6127]: Object .Gjs_ui_workspaceThumbnail_ThumbnailsBox (0x557cf8473220), has been already disposed — impossible to get any property from it.

Ok, this is not a problem of mutter, wayladn oder nvidia. The exceptionstack indicates a problem with a component, that is written in JavaScript! So i disabled all Gnome-Extensions and solved the problem!
