SUMMARY When you have two monitors side by side, and one is offset vertically, if the "primary" monitor is the higher of the two the secondary monitor has its wallpaper cut off. STEPS TO REPRODUCE 1. Set up two monitors in Plasma X11. Left at 0,0, right vertically offset by, say, 30% upwards. Configure suitable wallpapers on the monitors. 2. Reboot with auto-login enabled. OBSERVED RESULT The left-hand, lower, monitor will sometimes (though not always....) have the lower third of the wallpaper cut off. Changing the wallpaper does not fix it. However switching the left-hand monitor to be primary does fix it, then switching back to the right hand as primary the wallpaper remains intact. EXPECTED RESULT All the wallpaper....

I'm unable to reproduce this on X11 with 6.1.4 or git-master with the same settings Do you mind sharing a screenshot of the settings screen for the wallpaper on the secondary monitor (where the wallpaper is sometimes cut off)? I had the wallpaper set to an image that was scaled.

Better than that, I can show it with the wallpaper copping happening :) TLDOA: Layout: Folder View, Wallpaper type: Image Positioning: Scaled and Cropped Changing the positioning has no effect on the cropping.
Thank you for the screenshot and additional detail. I'm still not able to reproduce this, after quite a few reboots. Something I did notice is that when the wallpaper first loads, the image on the lower, smaller screen is cut off as in your screenshot. After a moment, the displays are redrawn and the wallpapers look normal. I'm guessing your system isn't doing that redraw, or it's not redrawing properly. I'll leave this open in case someone else is able to reproduce or dig further.
Out of curiosity, I tried reproducing with the specific wallpaper you're using, and I am seeing similar behavior. I set both displays to use that. I had tried a few other stock and custom-added wallpapers before, when I couldn't reproduce It is not necessary to enable auto-login I can reproduce on git-master, almost every login On my system, it's the larger / higher monitor where the wallpaper is cut off
It's a puzzler, for sure. I've done a bit more experimentation and, on my system: * It only does it if the right-hand monitor is higher than the left - the other way around and it's fine. * The higher one has to be primary. * I have tried different themes, including Breeze, and it's the same.

I tried moving the high right monitor to be on the left of the lower one instead of the right. The main problem vanished - so the high monitor has to be on the right. However in doing so lots of other strange things happened while editing the display settings - blank black wallpaper on one monitor at one point, one monitor with the wallpaper split in half and repeated, with my lower panel plonked in the middle of the screen, all very strange stuff.
