"Fit selection to width" does not fit into window. Audacity 3.0Audacity 3.0

In Audacity 3.0.0 on my Win7pro computer (enlarged Fonts, 125% , if it plays a role)
applying “Fit selection to width” leads to that the selection apparently sometimes does not exactly fit the visible wave window, such that playing the selection makes it scroll-jump, which is pretty uncomfortable.
Thanks for any ideas or taking care.
Best regards and thanks for extraordinarily useful and robust apllication!

Works fine for me on W10 with 3.0.0 and the latest Release Candidate build that I have for the upcoming 3.0.2 release.
