Cockpit sheen?

[gbtstr]

I could understand some significant glare from looking into the sun, and maybe from a couple of off angles. But, it seems to happen a lot more often than it should.

If the sun is at my back, I might get a little glare, but it shouldn't necessarily washout the whole windscreen - and not to mention the fricking back of the plane should be casting a nice shadow/blocking the sunlight anyway.
