When switching between workspaces, the wallpaper turns black if an application is open in full screen mode.

Hey there, I’m having an issue after updating to Taheo 26.0 on my M4 MacBook Pro. Whenever I switch between workspaces, I get a black wallpaper (in case I open an application in full screen mode). Could anyone please help me fix this?

I had a similar issue. For me I had to turn on 'Displays have separate Spaces' in the Desktop & Dock tab in Settings, for some reason that option toggled off during the update for me. You will have to restart your Mac. Hope this helps.
