Weird buffered rendering bug across different games

[VIRGIN KLM]

Hey everyone, I just wanted to post that weird bug I noticed around different games in possibility to narrow down what could cause such thing.

It looks like when you enable buffered rendering on some games you get exactly the same bug. It looks like a mirror-in-mirror effect or something like an effect like motion blur or bloom lightning not getting rendered or streched correctly to the screen.

Here's what it looks like:

See the pattern of the visual bug? It's exactly the same across those games but the games have nothing in common. (I remember Ridge Racer 2 was doing the same but it got fixed I think) Maybe it will help you understand how some games like GOW handle framebuffer.

Thanx for reading!
