Could you give a little bit more detail on why, what the side effects are ?

Sorry for late response, by default for NV12_UBWC is 128x32

Should this be a Fixes: ?

without this fix on V6, firmware throws below SFR
qcom-venus aa00000.video-codec: SFR message from FW: QC_IMAGE_VERSION_STRING=video-firmware.1.0-df9cb37cf8e507a4468265658702247652351a49

which result in playback happens through Software codec.
