Thanks for the report. Could you attach a zip file with a repro app so we're sure to discuss the same issue?

Hey @TCPcloudDEV thanks for the report and the sample 👍. For the next time, when you create a repro app, please do not remove any target (and especially Skia). Even if it does not compile, it's easier for us to check on all platforms.

Hey @Xiaoy312 this seems to be linked to https://github.com/unoplatform/uno/pull/11962 that you looked at recently with @ajpinedam

Xiaoy312 commented 1 year ago

the issue is android specific, (not reproducible on ios, and not implemented on other platforms...) related to #11962, but not necessarily a direct cause of this issue? note: VirtualizingPanelSmoothScroller is likely the area to look for
