Looks ok

Notepad app is in focus, floating panel dissapeared behind the Edge app

Floating Panel became very small and unreadable, clicking on it restores desired size

Rare occasion when photo of screens show more than screenshots - Meterials Panel on the laptop screen became very tiny, 4 times smaller to be exact
