Windows 10: Why does Windows 11 change my desktop background when I switch from "Extend" to "PC Screen...

I have a multi-monitor setup, and I have different desktop backgrounds set for the left and right monitors.Here's a color-coded illustration:left-wallpaper.pngright-wallpaper.pngOccasionally, I switch my Windows 11 PC to "PC Screen Only" mode by hitting Windows Key + P so that I can use the left monitor with my laptop.My issue is that whenever I switch back to "Extend" mode, the desktop background wallpaper on my left monitor is reset to whatever is on the right monitor:right-wallpaper.pngright-wallpaper.pngShouldn't the left monitor retain the wallpaper settings?

Desktop background changed to red

I just booted up my Windows 10 PC and logged in. But when I logged in, the desktop background changed to red, but the Lock Screen background was as normal. Everything worked fine, but the desktop background turned red.

I tried:

• Restarting the PC
  
• Resetting the background (to a picture)
  
• Changing the background to a different colour
  

All of them (except for the last one) didn't seem to fix the problem.

Does anyone know a fix to this?
