Runescape mad camera angles

Ever since RS 3 Gold went live, I’ve been experiencing the weirdest camera angles.
These normally happen in enclosed spaces, for example pyramid plunder, and when going over small hills/slopes, for example near the astral altar or the desert.

The camera itself seems to glitch out and go underground and the screen will either go blue or black depending on the reason.

It’s quite irritating, so can somebody explain whether this is just a general glitch that’s related to the beta or perhaps my own PC.
