Does this mean that it still runs slow when displaying remotely to a
HP X server, or that you see some rendering artifacts?

Could you please describe in more details the problem you're seeing
with the newer X servers?
Also, please list the exact configuration (client and server OS's,
whether they're fully patched, the framebuffer on the X server
machine).
A testcase would be really useful.
Also, what's your network bandwidth?

Unfortunately, there isn't much we can do about the performance
problem on remote X when using 2D rendering which includes reading
from the destinatuion surface (translucency effects, antialiasing).
As for the rendering artifacts you're seeing, we need more info
from you.
Also, we probably won't be able to help with the issues with HP X
server, you might want to contact HP regarding this.
Thank you,
Dmitri
