Top of the screen flickering when using glance after Cyan update

[WPCentral Question]

Guys,

I just updated. I have Lumia 920 with Cyan. I updated and now I see that the top 15 percent of the blank screen is flickering.. This is caused by glance as without glance when the screen it locked it is black. This was not there before I updated to Cyan.

Very disappointed.

Anyone has this issue?

Thanks
Rajeev
