I have a similar (the same?) problem with pd 0.39-2 in xubuntu. When I move windows I get alot of audio dropouts (even in very simple patches). I don't get any xruns and the cpu load is ok. What I do get is alot of DIO errors. The audio works fine when i run GEM in fullscreen.

Hello all,
I've been using pd on a fedora/CCRMA system for a couple of years with good results. Recently I decided to switch to Ubuntu for several reasons, and was aware that the latency wouldn't be as good as ccrma, but I thought it would be plenty sufficient for my needs.
However, after following the instructions on the ubuntu-studio page, pd still clicks and pops frequently, i.e. when moving windows or recording data or saving the patch. Increasing the frames/period in Jack helps a little, but not much... even at 512 or 1024! And no other settings seem to help (Realtime is enabled, and pd is launched with -rt).
Next I tried compiling a vanilla kernel with Molnar's patch as described on the ubuntu-studio page, everything works fine in that kernel, except no better performance from pd :(
This is the same machine as it was on ccrma, so it must be a software issue... any ideas??
