Description
Environment:
- OS:
VisionOS 1.1 - IceCubesApp version:
1.10.33
Description
Unlike macOS and iOS, Ice Cubes on Vision OS hitches a lot while scrolling the timeline.
I have forked and built Ice Cubes locally and there are several issues.
The first is related to LazyImage in AvatarView.swift. Removing this view and replacing it with Image(systemName: "square.and.arrow.up.on.square.fill") resolves most, but not all of the hangs on the main thread in instruments. I have not had time to investigate others.
I also did not have time to localize Nuke so that I could modify the source locally.
I did see some conversations on the Nuke repo related to worse caching and performance as of the most recent version due to the removal of optimizations in order to address some bugs.
I'll keep investigating as I have time.

Research direction
Start with AvatarView.swift and the LazyImage usage described in the report, then profile timeline scrolling and main-thread hangs with Instruments on VisionOS. Compare the VisionOS behavior with macOS and iOS, and inspect the reported Nuke caching and performance discussion. Done means the timeline scrolls without the reported hitches and the remaining hangs are understood or resolved.
