Hi,

I just installed osg and I tried the osganimate demo, on windows and linux. I'm 
observing that on fullscreen mode, when I zoom in or out, it appears a high 
pitch noise, probably from my graphics card ATI Radeon HD 5850 with frequency 
that depends on the distance from the object showed.

If I enable the VSync the noise disappears, with also the FPS.

I'm asking that here, because I'm getting it only with osg. In the past I 
worked with opengl, ogre, and I never got this issue.

What do you suggest me to do? 

Thank you very much for any kind of help.

Cheers.
