Blue Background with 3D on Macs

Worksheets rendered with 3D shapes appear with a dark blue background on some Mac computers in certain browsers. We have done extensive testing and it appears that computers with Chrome and Safari with AMD Radeon HD 5xxx and 6xxx series chips have the most trouble. We were only able to test on OS X Yosemite 10.10.5. Firefox, strangely, has no issues.


Multiple tests were done on different Macintosh computers including Macbook Pros, iMacs, and iPads. The majority (17/21 devices) had no issues. The only real similarity between the computers that didn't work were their hardware (i.e., age).


Web acceleration and WebGL were enabled.
