drillPick on mousemove not working with targetFrameRate as 6

Dear Cesium team,

I am initializing Cesium viewer with targetFrameRate as 6 and using drillpick on mousemove of the canvas. It is worked fine with Cesium 1.8 version. Now i am updated it to 1.12 drillpick giving 'kill pages error'. When I increased targetFrameRate as 30 it is working nicely but it consumes high CPU and battery drains too fast.

Even I have tested it in sandcastle throwing same error. Could you please help me on this.

Thanks,
Raghu.

Thanks Raghu, this is definitely a bug. I just open the following issue so that we take care of it: https://github.com/AnalyticalGraphicsInc/cesium/issues/2994

The issue was fixed in #3010 and will be in the 1.14 release.
