Wallpaper becomes black when swiping between applications running in full-screen

1. Hello to the Apple Support community,

I have recently updated to the macOS Tahoe (26.0 official release). I noticed that when switching between full-screen apps and the desktop, the wallpaper becomes black during the transition. Here is how it happens:

Swipe up with three fingers.

2. Swipe left or right with three fingers.

3. During this process, the background wallpaper becomes pure black until the action is finished.

I have never encountered this in previous versions of MacOS.

Does anyone have the same issue?

I am using a M4 MacBook Pro.

Thanks!

I have seen these types of glitches before...

Have you shut down and restarted more than once since your Upgrade(?)

—SafeBoot Start up your Mac in safe mode - Apple Support will sort many anomalies

Login and test. Reboot as normal and test.

— You can try Turning that FileVault off and compare your results

You can try changing the wallpaper and compare your results...
