Comment 12 for bug 996008

I'm having a similar issue in Saucy Salamander. After using my computer for a while, GUI slows down somewhat, not unusably slow, but animations are signficantly slower. Even the Window side by side snap animation shows a little lag, I begin to see the fade effect in icon right click menu in launcher bar where I did not notice it before, dash becomes slightly stiffer, etc. Dmesg | tail shows no irq messages for me, but hitting unity --replace solves the problem, until it occurs again. I like Unity but the desktop seems to be a mess with lots of users experiencing bugs either with the dash or with performance, etc.. I hope this issue is fixed soon.
