When a form with several TsScrollBars is first shown, the scroll bars initially flicker as white before they are rendered. There is no flicker after closing and opening the form again.
I've enabled all double buffering but that makes no difference.
I'm still finding this a problem in 11.23, although it seems to happen less often when the form is first shown, but more often when the form is shown again.
My app can have 50+ scroll bars at any time so this issue is quite important to me.
I think the issue may also affect group boxes and possible other controls as well.
