Needs some testing, but my assumption is that OBS doesn't like to play nice with the window itself resizing, and can't update that. A possible workaround would be to make the tracker invisible as opposed to changing the height, but I don't know if that is possible to implement, will have to look into it
Seems like there is an issue with OBS window capture when the tracker is minimized, here is a video someone took: https://www.youtube.com/watch?v=MLwJSsJswfE&feature=youtu.be
