Describe the bug

When device screen is rotating, there is a time window when the client sends touch events with incorrect screen size. These touch events are ignored by the server due to the incorrect screen size.

Normally this is fine, although the pointer stays on device screen, next time the mouse button is pressed, it's replaced by the new state. Except when the client side has a touch screen, because each finger has a different ID, the finger with ignored touch up event will stay permanently on device screen, causing incorrect behavior in apps. The only solution is to restart Scrcpy.

This can happen for example when user taps the full screen button in a video player, causing the screen to rotate. Or by releasing finger while using Alt + R to rotate the screen.
