10/17/2025, 5:13 PMWhen using ScreenScaffold with edgeButton on first display of the edge button there a big jump and lag (Worse than what seen in the video). Is this known and due to TLC ? From debug the intrinsicButtonHeight is properly set on first frame so not delayed.

10/17/2025, 5:23 PMNo debug on ultra fast emulator. Does not happen on any later fastscroll, just the first display. The scrollindicator clearly stops before the display then jump. I suspected it was the measurement of the button but it's properly done at start. Can't figureout what calculation / stuff is delayed 😞

10/17/2025, 5:25 PMDefinitely if its happening on devices on release builds raise a bug. There should be baseline profiles for key components built in

10/17/2025, 5:27 PMAdding a fake button at top to preload the edgebutton code seems to fix. So yes maybe the edge button is a really huge component. Will test thanks.
