Hi,

Laptop: Alienware M15 R6, 32GB Ram, CPU Intel i9, GPU Nvidia 3070,
Windows 11 Home, Antivirus: AVIRA
Windows, all drivers etc updated, all software updated, bios updated

in windows activated wallpaper slideshow, every 30 minutes with accent colour.
My Dock - see attached image.

problem:
The dock freezes regular and only the dock, i can move the mouse over the dock, but there is no reaction i can not click on icones on the doc, mouse over effect does not work. It takes around 5-20 seconds then it works just normal. During the freeze, cpu is in normal state.
Another applications like chrome, or on photo raw, Explore etc works fine

what could be the possible reason?
PLs help me, i like the dock, but with this problem i can not use it

my first suspicion is the last item on the right side:
internal command/desktop/Restore Wallpaper

5-20secs is hardly a freeze. Doesn't look like any Winstep issue - more likely Win 11 and latest updates. Also, a link in the dock to an internal command, when not in use, is completely idle, just like any other link.
