Hi, I'm new to the forum, but I'm a long time Sketchup user. I love the program dearly, even since Google got their hands on it, and I use it and Layout exclusively when designing and documenting houses. I just upgraded from a 2007 MacBookPro (MBP) running Snow Leopard to a new MacBookAir (MBA) (1.8Ghz i7 chip) running Lion. The MBA is sleek and smooth and beautiful and I found SU and LO faster and more responsive than on my MBP, but not phenomenally so. Out of the box, the MBA came with Lion 10.7.0 and I had no issues, it ran SU and LO well.
However, when I upgraded Lion to 10.7.1, I got the white line bug described in this thread. I don't know if this is a result of the internal Intel graphics chip on the MBA, or if all users running SU on Lion 10.7.1 are noticing it?
The MBA is faster than my four year old MBP, and the thing is so sleek and light and beautiful that I hate to do this, but I am returning it today. The speed improvement is just not substantial enough for me to deal with the white line bug. Instead, I'm going whole hog for the fastest iMac I can get. My theory is that as Google won't or can't substantially improve SU's speed on the software side, I'll just have to use as much muscle as I can purchase so I can continue to use my beloved SU and LO for my work. (if only it weren't forever doomed to 32bit single processor....)
Is anyone running SU on Liuon 10.7.1 and not getting the white line bug? I hope it's limited to the MBA.
