Big Sur Slider Control

Is there a way to stop the grab handle being clipped?

Built using 2021r1 or 2021r1.1. 2020r1 seems to render ok

looks like the NSControl’s frame height is always being set to 21, which is wrong.

calling this on open fixes it

slider2.NSControlMBS.frameHeight = slider2.Height


For tracking: <>

Also need to update after resizing controls
