@robllstevens from https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2169837 linked two upstream patches in his bug report that appear to fix some amdgpu graphical artifacts according to the comments. I'm not sure if this is the same issue, but I built a test kernel with the fixes applied in this PPA:
https://launchpad.net/~rossporter506/+archive/ubuntu/linux-generic Any feedback on whether this solves the problem would be appreciated. This kernel is entirely untested and unsigned (no good for devices running secure boot), so I should provide the usual disclaimer that this is just for testing purposes, not for use in production, etc., etc.. Install instructions: # 1. Add the PPA sudo apt-get update sudo apt-get install -y software-properties-common sudo add-apt-repository -y ppa:rossporter506/linux-generic sudo apt-get update # 2. Install the test kernel (LP#2169181 build) sudo apt-get install -y linux-image-unsigned-7.0.0-38-generic linux-headers-7.0.0-38-generic # 3. Reboot into it sudo reboot # 4. Check the kernel installed correctly uname -v # should read '#38+lp2169181v2-Ubuntu ...' -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2169181 Title: Visual background flickering and pixel artifacts after updating to kernel 7.0.0-38 (regression from 7.0.0-34) | Ubuntu 26.04 | AMD Radeon RX 9060 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2169181/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
