WebGL problems, input sluggish and standard shader errors

Hello! I am at home right now so I can't show a screenshot, but I will upload tomorrow.
I'm experiencing several issues with WebGL.

The major ones are:
The standard shader has very strange errors. I have a floor plane with low smoothness and the reflection is totally messed up (it looks like its being sucked into a vortex in the middle), and the smoothness looks like its incorrectly set to 1. The standard shaders on some of my meshes also have huge artifact that look a bit like banding but more severe.

The input from the mouse also seems sluggish. If I move it steadily from left to right the input seems to vary greatly; sometimes it moves very slow, and sometimes it moves a bit faster. The whole scene also jumps at times. I have a very strong gaming computer and the scene was quite simple.

I used the new deferred shading with FXAA on the camera.

Are these known issues?

 

Please file a bug through the bugreporter, with your project, so we can have a look.

 

Sure thing, I will tomorrow. So I take it Standard shader on Deferred on WebGL not working isn't a known issue then? As well as the input problem.
