Hi everybody here, 
and happy 2000000000000009 !!
I have a problem using Jack, Renoise, and the ATI proprio drivers…
I have 2-4 ms latency with an excellent sound and stability, even with songs full of tracks (18) and effects(80)…
My problem is when I move a window, or scrolling in Firefox for example, I have distortion in the playback.
And No Xrun in jack…
The sound seems to be distorded, and pitched down when i move a big window (a new hidden renoise effect)! lol
When I’m moving a small window with Renoise interface in background, it is ok, no problem…
When I’m working in Renoise, no video problem, just great sound!!
I have tested with Qtractor, Ardour, and the problem is there. (So it is not a Renoise’s fault)
Using just Alsa doesn’t give me this problem.
So I have changed my proprio ATI drivers for the Debian repos drivers (only 2D), and the problem
seems to be resolved.
Tested on the same computer, on Ubuntu 7.10, and 64studio distrib.
Using a fa-101 firewire audio interface.
Kernel 2.6.26.6-rt11
icewm or xfce4 or windowmaker
acpi=off
PAM configured
etc…
I have tested many IRQ configurations…always the same problem…
I have tested with Qtractor, Ardour, and the problem is there. (So it is not a Renoise fault)
The best results with Jack are there:

My questions are :
[b]- Is there a way to disable 3D graphics with ATI proprios drivers? But I think no…
- Are my IRQ configurations good? But i think yes…

Thanks a lot for your help …
