Dear team,


I would like to ask about alpha-blending of i.MX6SX.

My customer want to use alpha-blend feature of i.MX6SX.

They saw X-position could be slipped when alpha-blending is set.

The phenomenon occurs on MCIMX6SX-SDB with Yocto 4.1.15_1.1.0.

They set AS_ENABLE bit in LCDIFx_AS_CTRL register into 1 to enable alpha-blending.

They want to override the FB0 and FB1.

If other considerations than setting AS_ENABLE-bit are needed, please let me know.
