I've made some research on this forum and on google but couldn't find help anywhere, so I'm asking here. there's a process in Mac OS X called "windowserver" which is responsible for drawing the ui, from what I've read. Strangely this process is having is not acting well and is actually slowing down my system. It's taking alone about 50% of a processor every 2 to 3 seconds. During this time it goes down at around 3% but after it goes up and use half a processor, for nothing. I can actually sense it when I'm working under Photoshop or simply using my tablet, which is REALLY annoying. I can't solve it by rebooting. Does anyone has the same issue? Any answer to my problem?
