That is not surprising.
What is very surprising to me is that resolutions would need to be
divisible by 32 for things to work, that is an unusually large number.
You could try changing
> mpi2.width = mpi2.w;
to
> mpi2.width = (mpi2.w + 31) & ~31;
but that wastes quite a lot of space.
I forgot, which card/drivers are you using? I am using
"nVidia Corporation G70 [GeForce 7600 GS]" with driver version 169.12
