Hi everyone, I know there are a lot of threads about this, but as you can see from the title this is slightly different. I bought my macbook pro 13 inch retina last week, and I updated everything immediately (including software update) and I was so pleased to find out that there was no scroll lag whatsoever in some pretty heavy websites. But today I was using my mac on the same websites, and there is sooo much scroll lag on the same websites. How come? There were no updates in between and before there was no scroll lag, and now there is! Some websites still work fine, but lots of the ones I use regularly have scroll lag. Note that I noticed the scroll lag after I tried to connect with my TV using HDMI and played with the arrangement. But now it's disconnected, so that shouldn't have an effect right? So why is it showing up now?
