After upgrading to 10.10.4, Safari has been experiencing a weird graphics rendering glitch. The bug seems to involve WebGL, most notably when use Google Maps through Safari.
The symptom is the screen will quickly fade to black, and come back on. The animation is very similar to that when putting an app into full screen mode.
Here is a copy of the kernel panic from Console:

Can anyone make any sense of this? I am hoping it's a software glitch and not related to any hardware issues.
