Problem HUD blinks

[argus]

Hi.
I have this little but annying graphics problem. When the HUD overlaps the 2D cockpit, the HUD goes into a fast blink. If i scroll the cockpit down, the HUD is just fine. It is only when the HUD is on top of the cockpit there are any problems.

What could this be caused by, and how is it fixed?

I experienced similar problems when I had something running with the capability to display something on top of the screen. Something like fraps or "user friendly" overclocking utilities.

I get a blinking hud when anti-aliasing is on.
