SUMMARY After the timeout period where displays go into power saving mode after the computer is locked, waking from this state will often have plasmashell be in the software rendering mode, and also will have set the backend to software in kdeglobals. It may be related to my monitor having a deep power saving mode, where it will disconnect after an unspecified time, however I can't seem to replicate it consistently. I am also using an Nvidia 3070 Ti with official drivers. STEPS TO REPRODUCE 1. Have screens go into power saving mode 2. Wake computer 3. Observe Software Rendering notification in system tray 4. Observe scene backend in kdeglobals set to software OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
Sorry accidentally submitted before finishing the template OBSERVED RESULT Software Rendering notification in system tray and kdeglobals scene backend set to software, plus all the oddities that come with software rendering. EXPECTED RESULT Remains in automatic rendering mode when waking from power saving SOFTWARE/OS VERSIONS Linux: Nobara Linux 41, kernel 6.12.11-204.nobara KDE Plasma Version: 6.2.5 KDE Frameworks Version: 6.9.0 Qt Version: 6.8.1 ADDITIONAL INFORMATION
Hi - for what it's worth, I don't see this issue on my Fedora KDE 41 device with an NVIDIA card and proprietary drivers. Just to check - do you have multiple monitors? If so, does the issue also occur if only one monitor is attached? And does the issue occur if only the monitors power down, or does it happen when the overall device also enters a sleep state? Thanks!

I'm not entirely sure what changed but I haven't noticed this issue anymore, so I think I'll just call this resolved.
