For rollouts like this, a small holdback experiment is typical, to assess long term trends. Or maybe your browser doesn't have hardware acceleration enabled? Or you could be in canvas mode? Try ?force=webgl on the end of the maps url in case it's the latter. Try shadertoy.com to see if webgl is available.

Webgl works on my browser. Shaders work. Google maps is still flat. force=webgl does nothing. I'd say it's a partial roll out.

?force=webgl fixed it for me, thanks
