Hello,

Does the problem you mention occur when you switch directly
from RGBA 5551 to RGBA 5650 ? Does it also happen if you
switch to 32bpp RGB8888 or 8bpp CI8 in-between ?

I have a similar problem with pm3fb, if I change the RGBA
component but not the depth, colors are wrong, but changing
depth and back fix the problem. Maybe it's the same bug and
not directly related to the driver ?
