The app shouldn't freeze like that.

Screenshots

No response

NuGet package version

WinUI 3 - Windows App SDK 1.5.5: 1.5.240627000

Windows version

Windows 11 (22H2): Build 22621

Additional context

If there is no reproduction, try to increase the system workload.
Another way is to create an app with two sliders and move them simultaneously.

I can't reproduce. Can you share a screen recording? And how can you move two sliders simultaneously?

Do you have a server drive where I can upload a video?

You can just drag and drop a video in github (the file needs to be <10M. You can compress/transcode/lower the bitrate it if you exceed).
