Using my Pixel 2 I can get scrcpy to start and connect to my phone. The mirrored image of my phone pops up on my Windows 10 PC and ... then nothing. The image is just static and won't ever change from that first image when the window opened.

For mouse clicks something similar happens: it registers only a single click and none thereafter.

(Btw, the mouse click always seems to register as a long-press, no matter how fast I click)
