Summary: artifacts when doing glamo HW rotation
Product: OpenMoko
Version: current svn head
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P2
Component: kernel
AssignedTo: olv at openmoko.com

I got artifacts when hardware rotating (reg 0x1106) the screen with 90 or 270
degrees. It happens in both VGA and QVGA modes, when DCLK ratio is 2:1 or 3:1
(refer to svn rev. 3113).
It works fine in both modes when I raise DCLK ratio to 4:1. However, this gives
lower refresh rate. QVGA looks fine under this refresh rate, but VGA has
serious flicker issue, to my eyes.
