Prescaler not working

[UBERmonkeybot]

I cannot get prescaler to work reliably.I cannot increase screen by 2

e.g.

Game screen is @ 1280x800
Prescaler 2560,1600

so its 2 x  the original but is the size of the original
if i multiply by 1.5 then you can visually see that it is different.

I have read somewhere else that this may be a bug so have started a thread on it.

Anyone else experiencing weirdness,if not i will post my code

It's have been confirmed in a another thread. There is a issue with x2 scaling and only x2.
