Seems like you are doing the right things: lite-duty window manager [you 
are using windowmaker, correct?], -rt flag, etc.

I don't have any such problems, and I am using Pd version 0.37.1 devel 
with Fluxbox windowmanager under Gentoo on a laptop. I do notice that if 
I have another app running that does something with the screen space 
[the animations played in the Gkrellm2 system monitor, for example], 
then I get periodic interruptions of sound. However, I can use grids, 
sliders, and even open up subpatches and drag them around without fear 
of boo-boos.

So what is the differences between my system and yours? It could have 
something to do with PCI interrupts, I suppose. Where is your sound card 
and where is your video card in regards to IRQ assignments? Are you on a 
desktop or a laptop? What is your sound card and what is your video 
card? Can you reassign IRQs in the BIOS, or failing that, try the 
card-rearrangement-voodoo-dance? Low-latency and/or preemptive kernel 
patches? Kernel version? Need...more...information.... ;-)
