On the Amlogic GXL & GXM SoCs, a bug occurs on the primary plane when alpha is used where the alpha is not aligned with the pixel content. The workaround Amlogic implemented is to reset the OSD1 plane hardware block each time the plane is (re)enabled, solving the issue. In the reset, we still need to save the content of 2 registers which depends on the status of the plane, in addition to reload the scaler conversion matrix at the same time.
