[oe-users] motion overlay in Xserver-Kdrive

[christopher reder]

I have a custom AT91RM9200 board running Xserver-Kdrive 1.3 from
org.openembedded.dev branch.  This interfaces to the linux
framebuffer.  

When I use a mouse, or animate images on the screen, I can see artifacts
laid behind.  In debugging it, I can see that if I put in a solid color
where the 16 bits are "00 1F 00 1F" and run the mouse pointer over that
area, I see "1F 1F 1F 1F 00 1F 00 1F" as though it either wrote back the
incorrect location, or was using an incorrect endianness, or something
else.

This problem does NOT show up using tiny-x from a buildroot toolchain.

I want to be able to use OE and need to use OE for my development, but
can not locate what could be the configuration issue here.  I have
checked in kdrive-common and haven't seen anything and have searched
around the web for someone with a similar issue and haven't come up with
anything.

Can anyone give some guidance of things to look at or check into?  Any
info from Xdpyinfo that could be useful?  It all *looks* right, but it
doesn't act right.
