So that means that GBM backend is being used. That I have never tested on
the Pi. Though you could try kmssink. If you can reproduce the issue with
kmssink, pleas add -v and share the caps reported. That will be needed to
report the issue to the kernel devs.

If it's only an issue for GBM, some investigation will be needed. Maybe
build and run kmscube test app, to see if it's the drivers (Mesa or kernel)
or GStreamer.
