EXPECTED RESULT configuration is applied. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.27 KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.113.0 Qt Version: 5.15.11 Kernel Version: 6.2.0-39-generic (64-bit) Graphics Platform: X11 Processors: 20 × 13th Gen Intel® Core™ i5-13600K Memory: 31.1 GiB of RAM Graphics Processor: NVIDIA GeForce GTX 1060 6GB/PCIe/SSE2 Manufacturer: ASRock Product Name: Z690M-ITX/ax ADDITIONAL INFORMATION This bug might be a result of https://bugs.kde.org/show_bug.cgi?id=473219. The same behaviour manifests on the screen configuration after waking from sleep. i.e. the selected primary display in the settings does not match the actual primary display that the DE uses (at least to draw the taskbar panel). Changing the primary display and then changing it back was the reason I went into the settings to change the primary display in the first place.
Created attachment 164416 [details] configuration after waking The configuration displayed by the settings after waking makes no sense. The *actual* configuration the DE is using is what I configured before putting the computer to sleep, and is similar to the other screenshot.
Thanks for the bug report. Sorry it took us a while to get to it. Does it happen on Wayland too, or only X11?
