2D transitioner Chrome error

Hi!

When I change to 2D view, I get an error on Google Chrome: Uncaught RuntimeError: matrix is not invertible because its determinate is zero.

I think it’s happening since last Google Chrome update. On firefox there’s no problem.

Hi Tamy, unfortunately this is due to a change in Chrome on Windows with yesterday’s update (Firefox and non-Windows works fine) (see our issue here: https://github.com/AnalyticalGraphicsInc/cesium/issues/1047) The short version is that they changed the version of ANGLE they were using for shader compilation and it no longer optimizes out unused uniforms. This breaks all existing versions of Cesium. We have already addressed this issue at head of master so your best bet is to switch to that until b20 is released.

I have floated the idea of releasing b20 early, instead of waiting for the first. I’m not sure if anyone else on the team supports that idea though.
