Oh dear, I bet you have the fix for the Qt bug that made scrollbars invisible, and it probably didn't fully fix the issue. *enormous sigh*

Explicit binding for visible

This is a workaround.
after the qqc2 commit d0642867ab629daf36a1194274a74758111140be
the binding on visible gets broken at start by unhideOldItem
with a Binding which is both delayed and RestoreBindingOrValue
the binding survives correctly.

I think so. My system is fully update.
Comment 14 Nate Graham 2022-09-20 16:09:15 UTC 
Darn. Could you add a screenshow of where it's still happening? Or, a few, if it's still happening in multiple places?

also check for controlRoot.size > 0

When horizontal scrollbars appear with a width of the handle as big as
the scrollbar making it useless, it has a size of 0 rather than 1,
like usually vertical scrollbars do
