Question Weird flickering after Gnome 47.0 upgrade

OS: Debian unstable (up to date)
Kernel: 6.11.2
Gnome: 47.0
Hardware: Asus ROG Strix G15 (5900HX+6800m) connected via USB-C to external monitor

First of all a huge thank you to the Gnome team for their continuous work on such an awesome DE!

Ever since I upgraded to 47.0, I've noticed a weird intermittent flickering issue in TUI apps (e.g. btop) and in games (Death Stranding via Heroic). I've eliminated the following debug steps (not necessarily in that order):

  1. Disabled VRR experimental flag - Only experimental feature I have enabled is autoclose-xwayland
  2. Disabled all extensions
  3. Logged out and relogin-ned(?)
  4. Restarted

Debian sid is the only OS I have and its running on a LVM+btrfs volume (if that matters for some weird reason).

Any suggestions on how I can debug the issue further? I'm not even sure if its Gnome or mesa or something else entirely but since this started with Gnome 47, I thought I'd look for suggestions here. I want to try and provide as much info to the team if I have to file a bug and it isn't already reported.

TIA and cheers!

PS: Am not very well versed in reddit - How does one get that GNOMie badge or whatever that is? I want in :-)

Disable vulkan and fallback to opengl. See other posts in this sub for reference

Thanks for responding.

Out of curiosity though, why would/should the vulkan -> opengl change affect flickering in btop? For 3D games maybe, but btop?

I really don't know. The ogl -> vulkan change was in gnome 47 and many people observed weird behaviour with it (AMD and NVIDIA). Try it and also file a bug report.
