Loading images in browser causes JACK device to glitch/get stuck

Hi,

I'currently setting up my laptop for audio production.

My Problem: any 'graphical operation', that is, clicking on a dropdown menu etc, is
a) slow. even if there is nothing else running, there's a very high latency when clicking, say, Firefox' 'file' menu
b) causes audible sound glitches (NOT xruns in jack, the xrun count doesn't increase). 

The sound glitches are not recoreded (seemingly) but very unnverving. If i don't click anything,
there are no noises ...

I tried the proprietary nvidia driver, but that seemed even slower.

My CPU is already running at maximum (performance governor)

Anyone got a hint ?

System Details:
Core2Due (x86_64) / nvidia (using nouveau) / awesome-wm / 3.2.17-rt28 kernel

Audio Details:
Echo Audiofire 4 / ffado / ardour2 / jack 1.9.8 (8.7ms latency setting)

Hmm got this problem again ...

- loading an image in firefox listening to music (mplayer on terminal)
- sound glitch, Jack message : Audio Device got stuck.

Never, ever got this prolem w/ ubuntu (on same hardware) ... any advice ?

Config is same as above but newer kernel (3.4.4), tried everal kernels (rt etc) doesn't really seem to matter ...
