I am not using stable owo versions, I built one from the 1.20.3 branch myself to develop mods on mc 1.20.4.

Confirmed on the latest 1.20.3 branch.

While I haven't reverse-engineered your entire screen, this problem smells strongly like you nested some part of your component hierarchy into itself - there isn't (or shouldn't be) any other way for this kind of infinite recursion to appear given the framework's implementation of the mouse dragging handler

Hmm, I attached the debugger and found that this here is a scroll container. When I drag the scrollbar out of the screen, it set scrollbaring to true the first time onMouseDrag is called, after that the mouse x/y coordinate is no longer inside the scrollbar, so onMouseDrag goes to super (BaseParentComponent), and it checks the focused element, but the element is scroll container itself.

So I believe it could be an owolib bug
