I am currently on a project which requires the i.mx6dual board to display at 90 degrees rotation.
After searching through the forum, i manage to patch the kernel and successfully display at 90 degree rotation.
However, i found out that during full screen refreshing (example: change full screen from blue color to red color), the screen will shows staircasing-effects. This does not happens if no rotation at display.
Is it related to the performance of the IC and ROT module of the i.mx6? Is there anyway to improve the performance to eliminate the staircasing-effects?
I am using kernel 3.0.101.
