Title:
Screen artifacts on recent amd gpu with kernel > 5.11.0-11
Status in linux package in Ubuntu:
Confirmed
Bug description:
This is my first time filing a bug report, so apologies in advance for
any mistakes and please feel free to point me in the right direction.
I'm posting this for the kernel package because the problem is
reliably eliminated by downgrading to 5.11.0-11 and reliably returns
by upgrading to any greater version.
I've been testing Hirsute as my daily driver for a couple of weeks on
my PC with one of the recent AMD GPU's (6700XT). Everything was
running flawlessly until the kernel upgrade from 5.11.0-11 to
5.11.0-13. After the upgrade I had a lot of artifacts (flashing
squares of either the background or random colors) on the screen.
Example picture attached.
* I suspect it's only in parts that are being hardware-accelerated. Turning
off hardware acceleration in chrome, eliminated them in the content part of the
browser, but the windows title bar continues to be affected.
* The gnome panels and application menu also have random square artifacts
appearing and disappearing.
* The issue exists both in X11 and Wayland sessions.
* I see nothing out of the ordinary in dmesg or journalctl -r.
* Downgrading to kernel 5.11.0-11 eliminates the issue.
* I tried installing the latest mainline kernel (5.12-rc6), the issue
returned, so I downgraded to 5.11.0-11 again (which fixed it).
* To see if other packages I installed may be causing the issue, I did a
clean install of the latest daily iso (20210407) and can confirm the issue is
also in there.
I'm happy to provide more information or testing.
