Black squares in Safari
MacBook Pro with Retina display, OS X Yosemite (10.10)
Same exact problem here. Has happened since day 1 with Yosemite.
I even rebuilt the MacBook from scratch and it still happens: MacBook Pro (Retina, 15-inch, Early 2013), 2.7 GHz Intel Core i7, NVIDIA GeForce GT 650M 1024MB
Hasn't happened yet on my iMac (27-inch, Late 2009), 2.8 GHz Intel Core i7, ATI Radeon HD 4850 512 MB
Same here... on a late 2015 iMac Retina 4k 21.55-inch.
Same problem here, on two separate computers. Why won't someone from apple tell us how to fix it?
I continue to have this problem, but only when browsing Google. I think it may be a Google bug.
It happens intermittently when I close a tab to go back to the Google tab I was working from.
I have tried:
1. Disabling all Safari extensions: no help
2. Disabling Google instant results: no help
Safari 9.0.1, OS X 10.10.5
