Bug ID: 461094 Summary: Graphics and some graphics card functionality broken after computer is put to sleep for a long period of time. Classification: I don't know Product: kde Version: unspecified Platform: Other OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: general Assignee: unassigned-b...@kde.org Reporter: lolgoga...@gmail.com Target Milestone: --- Created attachment 153249 --> https://bugs.kde.org/attachment.cgi?id=153249&action=edit 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. -- You are receiving this mail because: You are watching all bug changes.
