regression/bisected/6.7rc1: Instead of desktop I see a horizontal flashing bar with a picture of the desktop background on white screen

This change has a DMCUB dependency - are you able to update your DMCUB version as well?

This version mismatch issue is something I'll need to fix in driver for Linux.

Thanks,

Alvin
