Not sure if this is going to help but I did notice with pd-l2ork on a laptop with an AMD video card (fglrx driver) when I have the  tearfree (vsync) option enabled pd-l2ork's gui gets very sluggish. Disabling the vsync option makes it fine.

Hello all,

I'm seeing a strange probelm with Pd. I'm testing a very simple patch
(total CPU load < 1.5% with DSP enabled). There are a few message boxes
used to set a hslider to some preset values. With DSP enabled they take
something like a second to respond to a click. What's wrong here ?
