I noticed a very small bug on 3.5.3.3540 and 22621.755. I have a Surface Laptop studio and when I switch between tablet and laptop mode the icons on the taskbar space out wider to make them easier to touch. The issue is when I go into tablet mode on occasion they will get wider normally but when I switch back to laptop mode instead of the spacing shrinking back to normal the icon spacing will become extra wide, even wider than in tablet mode. This doesn't happen every time. I tried a different user profile and also reinstalling SAB without settings. I also had it happen on the production 3.5.3 build.
Edit just to add my taskbar is on top, I have small icons, Large icon spacing and labels always shown.
