Oh and compiling for 6.0v7 (still!) on Linux.

Hi,
I'm wondering if you guys can give me some pointers in where I might
look to iron out a glitch in my DrawIop. So everything is generally
working as I want it, but I'm getting very small glitches in the
output. Could be in my code but I'm noticing the glitches change when
I use any knob, even those unconnected with the output which is a bit
odd. I've even added a null knob that does absolutely nothing just to
test this. Change this knob and my artifacts change.
So, what I'm trying to do first is work out why my output (albeit with
artifacts) is changing when I move unrelated controls. I'm assuming
certain things get updated on any knob change? I know it hard without
seeing code, but have you guys got any ideas what is called/updated
each time a knob is changed? If it helps, things don't change when
changing to a different frame, only when using a knob. Also, the
change in artifacts will change consistently, in other words if I move
a slider back and forth, the result will change consistently back and
forth, same artifact pattern for each value.
I've also tried emptying the output buffer with memset for each row
before filling it again to see if this affected things, but this is
crashing nuke,
memset(buffer, 0, (R - X) * sizeof(float));
This has kind of got me stumped.
