A strange graphical problem

[VladimirVSC]

Hello, there. I have a huge problem that seems nobody else has. Some games have an annoying screen flickering and artifacts. The games noticed affected: TLOZ Wind Waker - (screen flickering of different colours), Twilight princess - warning screen is invisible, random skybox artifacts and purple blinking, characters' eyeballs blinking and may totally dissapear; Metroid Prime games (the first and the second part, actually) - Samus armcannon flickers and dissapears sometimes; The Last Story - constant screen blinking. I told about this problem sometime before but the answer was: "We have noticed nothing. Maybe you do something funny with the synchronization?". But the problem takes place and i can nothing to do with it (and I don't even know what the hell could I do with this synchronization!). The 4.0.2 version works good but all the revisions after and release candidates has this problem. Help, please! About the settings: native resolution, Virtual XFB, Scaled EFB is disables, all enhancements are disabled, Bounding Box is disabled, Fast Mipmaps is disabled, Video backend is Direct3D.
