Flickering on dual screen setup, AMD GPU


I’ve updated my F39 deployment yesterday and this issue started happening: https://youtu.be/05jNKrtGAyM

The flickering happens only on one screen. Does this ring a bell to anyone?
Meanwhile I rolled back to previous deployment.

You don’t mention your amdgpu (or kernel) setup, but I have issues with kernel-6.8.4-100 in Fedora 38 with amdgpu on an Alienware m17 R5 AMD laptop (eDP 4K panel). Going back to kernel-6.7.11-100 seems to restore usability for me as well.

Yeah sorry about that. Tomorrow I’ll try again and gather the GPU/kernel informations.

This seems to be the culprit for me: kernel 6.7.10-200.fc39 → 6.8.4-200.fc39
Mesa version hasn’t changed (23.3.6-1.fc39) between both deployments.
My GPU is AMD Radeon RX 7700 XT (radeonsi, navi32)


Looks like a kernel regression then. Can you file a bug for the kernel in Fedora’s Bugzilla? Thanks



I am seeing exactly the same thing under Fedora 40 with Gnome with a 7900 xt GPU. After switching to a 6.7 kernel the random flickering is gone.

I hope kernel 6.9 fixes this issue after it is released to the Fedora Repos.

Installed newest build of 6.9 from the koji buildsystem https://koji.fedoraproject.org/koji/buildinfo?buildID=2457165 and did not observe any flickering until now.

After last Updates of Mesa and libdrm stack i have seen flickering even on kernel 6.9.2.

No problems in games, it just happens in the transition in gnome when pressing the super key like in the video in the first post.
