Does the uipanel have a max height?

Hi,

I am working on a (programmatic) GUI where I have made a custom scrollable panel. I do so by creating a parent panel, which contains a child panel which is larger in size, and change its position relative to the parent panel by scrolling the scroll bar or the scroll wheel. The child panel holds some uicontrols, which are sized relative to the child panel.

Everything works fine, but at some point, if the child panel has a height of over ~3840 pixels, things start to act strange. The uicontrols get smaller in size when the child panel is getting larger. My first guess is that the uipanel size is capped at about 3840, and that the relative sizing of the uicontrols is done with the true size, but the GUI only shows the capped version. Does anybody know if there is any limit on the uipanel's size?

Regards, Robert
