Using XF68_FBDevv-accel-ppc-19981204-2, I'm seeing some trashed pixels when

me like the BITBLTs are picking up bits from the framebuffer rather than from
the window.  xrefresh puts things back in order.

Well, bitblt's do pick up bits from the framebuffer and not from the system
memory. That's why it's called acceleration, the video card's graphics
engine does the moving of data within the framebuffer memory on behalf of
the X server. No idea why it does this, however, since -accel-ppc exits
on signal 11 (Segv) on my machine.
