[BUG] Browser windows resize when opened

Every time I open one of the windows to the right of the browser (My Tag, related tracks, information or sub browser), that window becomes wider. This is with Rekordbox 5.0.2 in EXPORT mode. Rekordbox 4.3.1 does not have this issue.

To reproduce, click on one of the window buttons a bunch of times, and you'll see that with each click, the left side of the corresponding window covers more and more of the browser.
