Created attachment 174098 [details] Screenshot of the Desktop Background with incorrectly scaled wallpaper SUMMARY After resuming from standby, the wallpaper is no longer correctly scaled. It does annoyingly not happen every single time, but ca. 50% of the time after resuming from standby. It's easy to fix by just reselecting the image in desktop settings. STEPS TO REPRODUCE 1. Send system to standby 2. Wakeup and log in 3. Observe Wallpaper OBSERVED RESULT Wallpaper no longer fills the screen but is incorrectly scaled EXPECTED RESULT Correctly scaled wallpaper as it was before entering standby SOFTWARE/OS VERSIONS Linux/KDE Plasma: Nobara Linux 40 KDE Plasma Version: 6.1.4 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION Session is running on Wayland
I reproduced it once by swapping primary screen, but is very finnicky, happen only at times
As Marco hinted at, are you using a multi-screen setup? If so, can you run `kscreen-doctor -o` before reproducing the issue, and again after?

I am using two screens with different resolutions. It's possible that it tries to use the same (lower) res wallpaper size for both? Anyway here is the kscreen-doctor output before standby and after with the bug being reproduced: Before Output: 1 DVI-D-1 enabled connected priority 2 DVI Modes: 0:1680x1050@60*! 1:1680x1050@60 2:1280x1024@75 3:1280x1024@60 4:1280x960@60 5:1152x864@75 6:1024x768@75 7:1024x768@70 8:1024x768@60 9:800x600@75 10:800x600@72 11:800x600@60 12:800x600@56 13:640x480@75 14:640x480@73 15:640x480@60 Geometry: 2048,102 1680x1050 Scale: 1 Rotation: 1 Overscan: 0 Vrr: incapable RgbRange: unknown HDR: incapable Wide Color Gamut: incapable ICC profile: none Color profile source: sRGB Output: 2 HDMI-A-1 enabled connected priority 1 HDMI Modes: 0:2560x1440@60*! 1:1920x1080@60 2:1920x1080@60 3:1920x1080@50 4:1680x1050@60 5:1600x900@60 6:1280x1024@75 7:1280x1024@60 8:1280x800@60 9:1280x720@60 10:1280x720@60 11:1280x720@50 12:1024x768@75 13:1024x768@60 14:800x600@75 15:800x600@60 16:720x576@50 17:720x480@60 18:640x480@75 19:640x480@60 20:640x480@60 Geometry: 0,0 2048x1152 Scale: 1.25 Rotation: 1 Overscan: 0 Vrr: incapable RgbRange: unknown HDR: incapable Wide Color Gamut: incapable ICC profile: none Color profile source: EDID After Output: 1 DVI-D-1 enabled connected priority 2 DVI Modes: 0:1680x1050@60*! 1:1680x1050@60 2:1280x1024@75 3:1280x1024@60 4:1280x960@60 5:1152x864@75 6:1024x768@75 7:1024x768@70 8:1024x768@60 9:800x600@75 10:800x600@72 11:800x600@60 12:800x600@56 13:640x480@75 14:640x480@73 15:640x480@60 Geometry: 2048,102 1680x1050 Scale: 1 Rotation: 1 Overscan: 0 Vrr: incapable RgbRange: unknown HDR: incapable Wide Color Gamut: incapable ICC profile: none Color profile source: sRGB Output: 2 HDMI-A-1 enabled connected priority 1 HDMI Modes: 0:2560x1440@60*! 1:1920x1080@60 2:1920x1080@60 3:1920x1080@50 4:1680x1050@60 5:1600x900@60 6:1280x1024@75 7:1280x1024@60 8:1280x800@60 9:1280x720@60 10:1280x720@60 11:1280x720@50 12:1024x768@75 13:1024x768@60 14:800x600@75 15:800x600@60 16:720x576@50 17:720x480@60 18:640x480@75 19:640x480@60 20:640x480@60 Geometry: 0,0 2048x1152 Scale: 1.25 Rotation: 1 Overscan: 0 Vrr: incapable RgbRange: unknown HDR: incapable Wide Color Gamut: incapable ICC profile: none Color profile source: EDID
Thanks. I see no change in the output, which means KWin and KScreen are doing their parts correctly. The issue must be in plasmashell. Any chance you can upgrade to Plasma 6.2 and see if it fixes the issue?

An additional observation though: so far I only observed this behaviour when I used the same (stock e.g. shipped with KDE) wallpaper for both screens. I have not yet seen the bug when I changed the wallpaper to a custom one on my main screen but will update this post when I see the issue again.

I am currently running 6.2 since a while and can confirm the bug still persists. Also widgets that were originally placed centered are left off-center after wake from standby due to the incorrect scaling. I am also running the latests Nvidia driver 565.77.
How about 6.3?
(In reply to Nate Graham from comment #8) > How about 6.3? Running 6.3.4 and have not yet run into this issue. I have not used standby a lot due to NVIDIA driver bugs after resuming so the sample size is still kinda low. Switched to AMD GPU recently and will keep monitoring it but so far not happened on 6.3.4.
