Virtual display problem created with scrcpy on lower android

[KSMaan45]

Environment

• OS: Archlinux
• Scrcpy version: 3.0
• Installation method: pacman
• Device model: Oppo A37 With LOS 17.1
• Android version: 10

when we try to launch any app from virtual display it launch on primary display with a toast app doesn't support to launch on secondary display but if we launch it with with adb shell it did launch on secondary display as show in first video with second attempt, otherway around if we manually create virtual display from developers options then launching a app with adb it launch on secondary display fine, so seems like there was some problem with virtual display trusted flag for android 10.

here are the videos :

OK, I have no control over this behavior. The virtual display creation from developer options is different (it keeps an overlay on the main display), so it probably calls some other code.

Out of curiosity, what happens with a mix of the two:

• start a new display with scrcpy --new-dsplay=1920x1080, keep it open
• mirror that new display with scrcpy --display-id=XX
• start an app from the second window
