Are you talking about SDL local?
If so, is your host a big endian machine and the guest a little endian?
What is the color depth and bpp of the guest (I assume that the host is
32bpp)?
As usual two good tests are to check the vnc case and a guest in 32bpp too.
I tried to repeat the "tree C:\" test on qemu i386 but I couldn't see
any significant difference.
