Created attachment 153249 [details] It is a screenshot of my Steam client that is suffering from this bug, it also has a pop-up error from OBS that says I cannot use the NVENC encoding on my graphics card (this is resolved by a reboot) When my desktop is put to sleep for a long period (by pressing ctrl + l then pressing the sleep button in SDDM), It will often make the wallpaper background nothing but a bunch of bands of different colors, this also happens to the desktop, although the desktop can simply be "fixed" by clicking around. Some applications also suffer because of this, the Steam client becomes a mess, everything becomes different colors similar to the lock screen and desktop, but even after clicking around to "fix" this, Steam will then continue to only render videos on pages, everything else being black, for example on profiles or store pages, this carries onto the steam overlay as well, and some drop-down menus at the top of the steam client or the friends list, they will just become black boxes with no text or buttons visible. Some graphics card functionality also becomes unusable until reboot, for example when this happens sometimes I cannot use any NVENC encoding in OBS, it reports an unknown error and to check if my video drivers are up-to-date (they are). Besides that, sometimes the browser just becomes completely black as well, clicking around after a long sleep fixes this as well, but this can re-occur when opening a game in full-screen for example. Most other applications from what I can see, are not impacted, for example Discord doesn't suffer any of these issues despite me running it with GPU acceleration enabled. I suspect the issue lies somewhere with how the GPU is "woken up"? for a lack of a better term, despite this, I do *not* notice any performance issues in games after a long sleep. STEPS TO REPRODUCE 1. lock screen for a long period of time, over night 2. wake up computer, login OBSERVED RESULT color bands everywhere, applications not working correctly, unable to encode streams. EXPECTED RESULT A normal desktop experience with working applications SOFTWARE/OS VERSIONS Linux: Void Linux with kernel version 5.19.16_1 KDE Plasma Version: 5.26.0 KDE Frameworks Version: 5.98.0 Qt Version: 5.15.5 ADDITIONAL INFORMATION I tested out some other DE's and WM's including Gnome, XFCE4 and Fluxbox over the period of a few days each at the minimum, and none of them had any of these issues. Image of the issue happening is attached. Thanks.
NVIDIA, I assume? Probably driver issues, but I'll let the KWin folks confirm.
(In reply to Nate Graham from comment #1) > NVIDIA, I assume? > > Probably driver issues, but I'll let the KWin folks confirm. I should have specified this, Yes. It is an NVIDIA GTX 1070 ti GPU with driver version 515.65.01
Recently I updated my system, I am now running: KDE Plasma Version: 5.26.2 KDE Frameworks Version: 5.99.0 QT version: 5.15.5 Kernel Version: 5.19.17_1 behavior has changed a bit, I no longer face the color-banding issue from what i can see, however when i wake up my computer after a long period of time, i now get a notification popup saying that klwin had some graphical issues and has restarted. I do not notice any differences or issues at all.
These are all unfortunately issues with the NVIDIA GPU driver. :( Please report this issue to the NVIDIA folks, either by sending an email to linux-bugs@nvidia.com or making a post at https://forums.developer.nvidia.com/c/gpu-graphics/linux/ It would be helpful to the NVIDIA developers if you could run nvidia-bug-report.sh and attach the resulting file in your report. Thanks!
