UX issues with scrolling ListViews on iOS 26

[tomasMizera]

The scrolling behavior somehow feels unnatural on iOS - the project list it is quite laggy, and the list of features makes some sudden jumps. It works fine on places where ScrollView is used, e. g. the settings page.

Build: 2025.6.0
iOS: 26.0.1

Maybe related to #4128?

Maybe this issue will be solved by migrating to Qt 6.10, as that version contains some bugfixes for the new iOS.

@tomasMizera I suspect it is the same ListView issue caused by keeping cacheBuffer at 0 as a workaround for the Qt bug, which makes the scrolling stutter. Since cacheBuffer = 0 is used across all our ListViews, I am assuming a bit change there might work

Looks like the cacheBuffer property in list views didn't solve this. Let's see if improvements in Qt 6.10 fix this
