SUMMARY
When restoring displays the wallpaper appears in the upper left of the display (probably 640x480 rectangle on 2560x1440 display). 

STEPS TO REPRODUCE
1. lock your screens.  Here the primary in DP (1440) and the secondary HDMI (1080)
2. Either move the mouse or press a key to wake the displays

OBSERVED RESULT
the wall paper is displayed in what is probably a 640x480 rectangle in the upper left, the rest of the display is black,. Desktop right clicks only work when the mouse is clicked on the wallpaper.  Other windows are displayed correctly. 
Alt+f2 (so far) causes the wallpaper to be resized to 2560x1440.

This does not happen all the time.  possibly related to 484037.

EXPECTED RESULT
the display should restore with the correct wallpaper size

SOFTWARE/OS VERSIONS
Windows: 
macOS: 
Linux/KDE Plasma: 6.9.5 
(available in About System)
KDE Plasma Version: 6.1.0 (arch extra-testing)
KDE Frameworks Version: 6.3.0
Qt Version: 6.7.1

ADDITIONAL INFORMATION
in one case, the display was all black with no wallpaper and two mouse pointers on the display, neither working.  Using Alt+f2 displayed nothing, but blind typing kscreen-doctor output.DP-1.mode.1 restored the display.

> x11 or wayland?

wayland (sorry to have missing including that bit of info).  btw, I have had numerous occurrences when the unlocked DP display is black with two copies of the cursor, fast way to 'fix' this is to relock the screen (I have a shortcut setup) and unlock it a second time.   However the primary symptom remains the same.

Screen shot if display with wallpaper in left hand corner after unlock

Comment 5 Ed Tomlinson 2024-06-26 16:54:03 UTC

The windows work normally.  You can only get a desktop context menu by left clicking on the wallpaper in the upper left.

Comment 6 Nate Graham 2024-06-26 22:09:11 UTC

Similar to Bug 487717, which is fixed in Plasma 6.1.0 Also to Bug 484037, yeah.
