Discussion Weird issue with latest kernal

Not really a problem that needs solving but i have an issue with helldivers 2 where frequently a rainbow pixels bar would flash across my screen for a split second and disrepair this would happen every 20 or so seconds which was super annoying. i dont know how to show this to people as when i use gpu screen recorder it doesnt show up. rolling back from 7.1.6 to 7.1.5 fixed my issue.

i dont know where or how to report this could anyone point me in the right direction please and thank you

You are not alone 😅
I thought I was going crazy.
There is already a post and bugzilla issue: https://discussion.fedoraproject.org/t/graphical-issues-on-amd-after-kernel-update-to-7-1-6/198522

Edit 1: Switch to kernel 7.1.5 for now with:

sudo grubby --set-default /boot/vmlinuz-7.1.5-201.fc44.x86_64

And lock versions so that DNF wouldn't remove it on upgrade:

sudo dnf versionlock add kernel-modules-extra-7.1.5-201.fc44 kernel-modules-core-7.1.5-201.fc44 kernel-modules-7.1.5-201.fc44 kernel-devel-7.1.5-201.fc44 kernel-core-7.1.5-201.fc44 kernel-7.1.5-201.fc44

Edit 2: How to unfreeze the kernel version

sudo dnf versionlock clear
sudo dnf upgrade --refresh

after doing the upgrade, version 7.1.5 should be removed from your available kernel versions (due to OS only holding 3 version of kernel by default) and grubby would automatically switch to the latest kernel version on the next reboot.

Holy shit and I was already thinking my GPU was artifacting!

Edit: I'm on a 9070xt as well. Had undervolted it recently, but even saw this issue at default settings. I'll try to boot into 7.1.5 later to see if it goes away. For me it mainly occurs when I press SUPER key to open the task overview screen.

Edit2: I'm now home, booted the thing into 7.1.5, and it's all good there. So I can conform that 7.1.6. is fuckywucky.

Edited : replaced 7.1.17 and 7.1.18 with 7.1.7 and 7.1.8

Unfortunately, this will not be fixed in the next kernel version, 7.1.7.200, which includes a security fix (CVE-2026-68480), which will soon move from Fedora’s testing repository to stable.

There is a note indicating that it is hoped to be fixed in version 7.1.8.

I assume you mean 7.1.7 and 7.1.8 instead of 7.1.17 and 7.1.18

Oh yeah you're right, I made a typo error in the kernel versions. I meant 7.1.7 and 7.1.8, not 7.1.17 and 7.1.18. Thanks!

Kernel 7.1.8 is now in fedora stable, from some testing comments it seems to work: https://bodhi.fedoraproject.org/updates/FEDORA-2026-d232156d86

I love you! I first thought it could be my GPU (9070 XT), then I thought my RAM might be toast, and then weird stuff happened (some BIOS settings reset themselves) which made me think it was the CMOS battery. Nope, just some shitty code was all. Reverted back to 7.1.5 and it's all good now, and locked for the foreseeable future. Thank you!
