Problem of screen rotating

Since some days, I have a strange thing on my No1D5: when launching an android application, or"Settings", or “Alarm”, etc., the screen rotate of 90° clockwise, so the top of the screen is at the physical button side.

Any tip to recover the normal viewing behaviour of the watch with apps?

Edit: sorry for the upper text, the problem as disappeared, once having disconnected the watch from the PC via USB. It may be just a normal thing when having “Vysor” active…
