Scaling works, but not after restart

After changing the scaling from default to default+1, the layout is perfect. If I restart it as default+1 the window border disappears and the window is too large. Changing the scaling back to default, restarting and changing it again to default+1 produces a good layout.

Any idea on how to fix this? Using the scaling as default produces too small text and icons, resulting in unused space aswel.

do you actually mean 101 % scaling?

I mean the next ‘notch’ on the sliding scale.
