SUMMARY I have multiple monitors on my setup and I have the wallpapers on each one set to "slideshow" with the "random" order. All of these have the same directory set as the source and the same interval. Because of the random nature of the slideshows, it's possible for two monitors to show the same wallpaper at the same time. Can this be fixed? STEPS TO REPRODUCE 1. Have multiple monitors on your computer 2. On two or more monitors, set up a random-order wallpaper slideshow of the same directory or at least containing the same wallpapers 3. Wait, due to the random nature of the slideshow, it's possible to show the same wallpaper. OBSERVED RESULT The same wallpaper may be shown on multiple monitors. EXPECTED RESULT The same wallpaper may not appear on two monitors at the same time. SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.1.24-1-lts (available in About System) KDE Plasma Version: 5.27.4 KDE Frameworks Version: 5.105.0 Qt Version: 5.15.9 ADDITIONAL INFORMATION This is a pretty show priority request, I understand that completely. If my math is right, then if I have 10 wallpapers in the set and two monitors, then the probability that both monitors display the same wallpaper is 10%, so only 10% of the time that I am looking at my desktop wallpaper I can even notice this issue. So consider it not very high on the priority list, hence the minor status of this bug report.
Anything is possible in theory, but yeah, I suspect the effort-to-reward radio here might not be very high. Fushan, what do you think, can we do this easily? If not, I'd suggest closing it.
I asked GPT and it provides a method that should be no that hard to implement. Will look into it when I am not too busy.
The problem is that not all slideshow plugins will have the same directories, so I am not sure it can be fixed without adding too much code.
