Description Álvaro M. 2023-08-07 19:17:09 UTC

SUMMARY
Using two monitors with different sizes. Randomly (I haven't been able to replicate manually), the desktop background in the bigger monitor will change to the one with smaller resolution. I've uploaded images with the issue, and how it normally looks.


STEPS TO REPRODUCE
Can't seem to replicate it manually, don't know which logs to look for.

OBSERVED RESULT
Background image (or the whole desktop background, really) changes at random. 

EXPECTED RESULT
Background image size shouldn't change

Thanks for moving this to plasmashell. I've uploaded a log from KSystemLog with the most recent error.

Sorry it took us so long to get to this. I can't reproduce it in current git master, which will shortly become Plasma 6.3. Are you still able to reproduce the issue in Plasma 6.2.5 or later? Thanks!

I’m sorry, I’ve since upgraded my desktop and have two monitors with the same native resolution, so I’m unable to test this 🙁

Ok, thanks anyway!
