I was trying to deploy this app on an embedded system built over the yocto project (link).

The app works fine on desktop but on raspberrypi 4 mod B, once the video starts to be played the UI becomes black as in picture. The video is reproduced properly.

Embedded linux system build with yocto for raspberry pi 4 Mod B

I run the app from the serial console and I got these log:
