Reproduce the report by running scrcpy 1.16 on macOS with an Oculus Quest 2 running Android 10, using the startup log and attached screenshot as the baseline. Trace the screen-mirroring startup path from the reported renderer and initial texture messages; done means the Quest 2 display is visible instead of black.
