Sascha,

I applied v10 on 5.17.2 and...can't see difference.
I still need to play with zpos to get ui screen.
if i have playback - no OSD.
If I have OSD - no playback.

Maybe fix needs some adjustments for 3566? 

Here is short summary of playings with zpos and kms plane in Qt:

QT_QPA_EGLFS_KMS_ZPOS, QT_QPA_EGLFS_KMS_PLANE_INDEX

0,0 - GUI=ok, playback=ok, OSD=nok
1,0 - GUI=ok, playback=nok, OSD=ok
2,0 - GUI=ok, playback=nok, OSD=ok

0,1 - GUI=ok, playback=nok, OSD=ok
1,1 - GUI=ok, playback=nok, OSD=ok
2,1 - GUI=ok, playback=nok, OSD=ok

0,2 - GUI=nok, playback=n/a, OSD=n/a
1,2 - GUI=nok, playback=n/a, OSD=n/a
2,2 - GUI=nok, playback=n/a, OSD=n/a
