Bad: \"More clustering options\".

The following steps consistently reproduce the issue on both Note3 (running 4.4.2) and Samung Galaxy Tablet (running 6.x).\r\n\r\n 1. Open a GL JS Samples page.\r\n 2. Lock the device.\r\n 3. Unlock the device after half an hour. All text and icons are now rendered as black rectangular patches. Sometimes you may have to pan/interact with the map to cause these to appear. I've attached a screenshot from my device.\r\n\r\n![screenshot_2016-10-31-11-50-11](https://cloud.githubusercontent.com/assets/8890269/19867585/997c76b2-9f61-11e6-99c5-37a53fc63411.png)\r\n\r\n\r\n### Expected Behavior\r\nText and icons should be rendered correctly.\r\n### Actual Behavior\r\nText and icons are  rendered as black patches.\r\n"}}
