Video artifacts when mirroring from iOS device but not macOS device

[dustinlieu]

I'm running RPiPlay on an Ubuntu VM. I get major video artifacts when mirroring from an iOS device but not from a macOS device. When I set displays_0_overscanned_node to 0 in lib/raop_handlers.h, it fixes the diagonal shifting effect, but there are still problems with the colors.

Default:

With overscan disabled:

When I change the resolution in lib/raop_handlers.h to 1280x720 it displays perfectly. Not sure why it only messes up at 1920x1080.

I also encountered this with Ubuntu in VirtualBox, I had to both disable overscan and set the resolution to exactly that of the iOS device:
