Does anyone have any idea as to why this may be? What is it that would cause the rdesktop windows to be so "chunky" and slow when redrawing vs. the perfect operation under Tiger? I'm not familiar with the internals of X11, so I don't really have the skills to help troubleshoot this. I wish I did. I will also send an email to the guys running rdesktop and see what they think. If I receive a response from them, I'll post it here as well.
I recommend checking whether this might be due to deferred graphic updates.
You'll want to install the developer tools if you haven't already.
Launch Quartz Debug, select Tools / Show Beam Sync Tools (Cmd-B),
and select "Disable Beam Synchronization", does the issue with rdesktop improve ?
If so, then rdesktop or X11 will have to reduce the number of graphic flushes it does.
If not, run Shark and collect two profiles while running rdesktop:
Time Profile (All Thread States) / Everything
System Trace / Everything.
If you send them to me (*not* to the list, those files can be very large), I'll see if I can spot
anything interesting and post my findings. No promise that I'll find anything worthwhile,
but I'll give it a go.

Thanks,

Ditto. rdesktop is painfully slow on this release.

I have seen the same problem with rdesktop and vncviewer. It's very frustrating.

I don't know if it's related, but in Gimp.app if you select the
paintbrush tool and move the pointer around in an image the mouse
tracking is *extremely* slow. I guess I'm just potentially confirming
this report.
