Some sub-menus and context menus are showing scroll arrows at the top and bottom despite there being plenty of room on the screen to display the full menu. This only seems to happen when display scaling in the Windows display settings is set to 125% and not 100% (I haven’t tried other settings).
Okay, I just had a look and it seems like we missed the change when preparing the 1.0.0-rc.17 release, because the fix is in a separate library. It will be in the new release, though (probably today or tomorrow).
