Hi,

supposing there is no way to keep the X server from falling back to
unaccelerated code: why are the mythtv menues the only affected ones?
Even if the drawing code runs incredible long. Why does it affect the
processing of keystrokes? Let's say it's the X server. Again, I can't
reproduce this "bounce effect" in any other application.

Kind regards,
