Samsung Wireless DeX Flowing Mouse Issue.

I will use Samsung DeX by using the Wireless DeX over Miracast feature, then capturing the DeX display using scrcpy. I will use the -M parameter to use the mouse as a UHID input on DeX. I have found that if you have flow pointer to phone enabled in DeX, and you try to move your mouse from DeX to the phone screen, it will glitch to the center of the DeX display the first time. However, the second time I try to move the mouse to the phone screen, the phone freezes, and then reboots. Previous versions of scrcpy did not have this problem, but some of the latest builds have this issue. I have also tried this on another phone with Wireless DeX, and the same thing happens. I have tried to use the --new-display parameter, but the desktop environment is not fully developed yet, so there are some features from the old experimental desktop option in Android Developer Options. My phone is running Android 16, and I am using scrcpy build v3.3.3. I miss the old DeX for PC app, and this is the closest way to do it now. Keep up the good work!

Reproduce with Wireless DeX over Miracast, scrcpy v3.3.3, the -M option, and DeX pointer flow enabled, then compare against earlier builds. The issue is done when moving the pointer between DeX and the phone no longer glitches, freezes, or reboots the phone.
