choppy expose

[chochocho]

Hi,

I have a problem with my early 2011 macbook pro i7 2.2ghz,

While I was watching a youtube video I noticed that my expose started to become choppy, I restarted my laptop hoping that it will solve my problem but nope, I'm stuck with this problem since yesterday, I googled and found some info about the quartz debugger, I don't want to do that, I tried resetting my PRAM too but that didn't help either,

I have no idea why this happened, I did some after effects rendering and some autocad drawings.

Any solutions? I might be nitpicking but it is really annoying and I don't want to format my hdd and install snow leopard again.

It's only been 2 months since I bought my laptop.

What does activity monitor look like? Are there any runaway processes chewing up CPU time?

Hi,

Activity monitor seemed to be normal,

I reinstalled snow leopard, problem solved.

and it's back!

man, this is really annoying, I formatted my harddisk and reinstalled snow leopard 2 days ago, everything was fine for 2 days and now the choppy expose is back!

any suggestions?
