I was going to open a new topic but this one seems closest to what I am seeing.
For me to reproduce, a resolution change has to occur (as per @F_Behrens). It most often reproduces when I wake the laptop from suspend as the lock screen is not using the same DM (I think?!) as the desktop session.
However this only seems to occur when I have an external monitor connected. So I am not sure whether that is a contributing factor.
I have two 1440p displays connected. One goes in via USB-C, the other monitor is connected to the first via daisy-chain.
I see exactly the same on my external monitor (internal monitor sadly does not work). Fully updated Fedora 39 Beta. So far it only happened when starting games through Steam but otherwise I did not do a lot yet on that machine.
I think the problem will go away after moving to Fedora 39 stable. Think we can rely on that However, the error also occurs without an external monitor.
Something similar is happening to my Ryzen Framework on Fedora 39 Silverblue.
Whatās odd is that it doesnāt happen in xOrg, Wayland only.
While on Wayland, it only happens if I run my internal display at the native resolution. If I lower the resolution of the display, there are no graphical glitches.
This happens even after I added the kernel parameters mentioned by @F_Behrens
I was experiencing this pretty consistently by launching a fullscreen 3d game from steam (elden ring, surprisingly runs quite well) at a lower resolution. Things seem to run fine, but after tabbing out, the white flickering appears. kernel log shows:
I am on F39 with 6.5.8-300 kernel and I go the white blocking artifacts once so far today. I ran sudo grubby --args="amdgpu.sg_display=0" --update-kernel=ALL and rebooted. Iāll see how it behaves.
Pure anecdata, but this seems to have improved the situation on my system. Bios 3.03, Kernal 6.5.7. Iām running an external 4k display through a thunderbolt 3 dock.
The BIOS update 3.03 solved the problem for me. There are no more graphical artifacts. Chrome does not crash anymore either. However, it still happens that all programs are terminated and the system logs me out during higher loads, e.g. games. I can imagine that this will be solved over time by an update of the operating system.
I have not. I think thatās probably going to be an upstream amdgpu bug.
Iāve seen it only when using mulitple monitors, it affects multiple monitors. It MAY be with one using fractional scalingā¦I donāt remember the circumstances. Itās also harder to replicate with 3.03 seeming to have drastically reduced the occurences for me (only once since I updated).
Gotcha, this may indeed be an issue with multiple displays and perhaps even with how the displays are connected. If it reoccurs, worth a bug report as I have not experienced it.
@Matt_Hartley hate to be the bearer of bad news but after upgrading to the 3.03 BIOS, the problem is worse and now happens on the regular monitor with no external monitors connected at all.
This sounds like a hardware issue as I am not seeing this here on two separate units. What is your update status (last time updated) and which kernel is in use again?
Edit: Iām doing a clean install now and retesting to see if a bug cropped up.
This AM opened lid and was unable to wake. Rebooted and updated (dnf update), later laptop suspended after inactivity, and when woken, display was flickering.
Linux devnull 6.5.7-300.fc39.x86_64 #1 SMP PREEMPT_DYNAMIC Wed Oct 11 04:19:02 UTC 2023 x86_64 GNU/Linux
Just did a clean install, running current kernel 6.5.9-300.fc39.x86_64 - suspended and resumed multiple times without issue. Logs reflect successful resuming as well.
Are you like Tim, attached to external displays as well? If so, how are the displays connected (expansion cards, HDMI or DP)?
However, the error also occurs without an external monitor.
