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

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:

1. 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!

Yingyu
