i run NR v1.1.3 on a [EDIT] RPI 3B with Raspbian
i open the NR editor with chrome 85.0.4183.102 (Build officiel) (64 bits) on a win10 (2004 home) PC.
And this is what I often encounter:
clicking in the right menu makes the menu jump but does not react. Then reacts shortly after.
I display on the left part of the screen the dashboard and on the right the NR editor. (By pushing a window towards an edge of the screen, it is automatically positioned on half of the screen)
Do you need more details?
