Sometimes when resuming from sleep, or when playing a fullscreen video, my screen will fill with white video blocks. If I switch to a virtual terminal and back to my GNOME session, the corruption goes away. Similarly, rebooting will fix the problem (until it appears again).
I passed a memtest86+ last night after thinking this might be caused by memory problems.
Interesting, has this been occurring since day of the installation or after a recent update? Also is this occurring with external displays attached to a dock (or expansion cards as this would be ideal) or just with the internal display? Looking to try and duplicate.
After looking at the other thread, this does look like similar corruption (although no translucent blocks like in the first image). Interestingly this isn’t happening with >= 64GB RAM or with external monitors attached. I can try the sg_display=0 kernel cmdline option to see if it helps.
I enabled fedora-updates-testing with includepkgs=kernel* kernel-modules* linux-firmware* *-firmware to test 6.5.9. So far I haven’t gotten the artifacts to reproduce yet, although sometimes it takes a while. If it does I’ll try the sg_display=0 option.
Been trying to replicate this myself to see if we need to file a bug. This is Fedora with external displays, correct? I have not had any issues (single display, internal) with distortion on resume. If this is in another thread (and I remember seeing this today), I can answer it there as well once I get the requested details.
I have graphical artifacts on my display from time to time. These occur when I open videos, start a game via Steam or sporadically from time to time. Has anyone else experienced anything like this? Other than that, the system is stable.
I suppose it could be either the beta version of Fedora or the still very new drivers. At this point, I hope it can’t be a hardware defect.
If you have a lot of ram (64GB+), could it possibly be related to this issue?
Linux support for 64GB (Inclusive) and higher RAM capacities may cause white/blank screen issues with displays on some distributions with kernels below 6.5. Ubuntu OEM kernel oem-6.1-1021 and later has a backported workaround. For other distributions, please verify you are using 6.5 or utilize the following patch if you experience this issue:
Same artifacts here. It seems almost whenever display space changes (resolution change or display added/removed) they appear. Good thing KDE has such a robust session management, I have restarted it more in one day than in weeks before.
If you can capture logs I would recommend reporting this as an official bug / compatibility issue. No reason for a workaround when things should “just work” on a supported distro. It could signal a broader issue that may need to be fixed.
I had a similar issue but have not been able to reproduce. Happened to me waking from sleep.
