I'm okay with reverting the patch, but I want to see the requested data 
and tests first. I could not reproduce this issue on my side, and others 
did not see it either. I suspect this is something related to firmware 
or it is a display-specific issue, that's why the data/test that I 
requested would be useful.

Thanks
