gralloc4: lockBuffer: and unlockBuffer: messages make using debug messages impossible

I bought a A8 galaxy tablet. In my app with camera active the camera works but there is a stream of

I gralloc4: lockBuffer: id=27700000614, vaddr=0x7b8b0ea000
I gralloc4: unlockBuffer: id=27700000626, vaddr=0x7b815d8000
I gralloc4: lockBuffer: id=27700000618, vaddr=0x7b8a75b000
I gralloc4: unlockBuffer: id=27700000614, vaddr=0x7b8b0ea000
I gralloc4: lockBuffer: id=27700000621, vaddr=0x7c28816000

making using the application output for debugging impossible.

I then built the example camera project in Qt 6.4.3 and there was some messages but they stopped in a bit.

I build the camera example in  Qt 6.6.0 and it had continuous stream of the gralloc4: messages.
