distorted image with NVIDIA

[sakoula]

Hello,
I have installed osx on a HP Compaq Elite 8300 which has an:
- [email protected]
- NVIDIA Quadro NVS 300 512 MB.

I use the stock apple driver, chameleon with 'GraphicsEnabler=Yes' and everything works fine but with a small problem.

Sometimes the image I see within a browser or within a Virtual machine is distorted. This is not happening on the whole screen but on a part of it (but not always). What is interesting is that I managed to grab it with Grab.app and I attached a screen-shot.

I do not get any message on the console when this is happening.

This happened rarely on mavericks but it is now very often on yosemite.

Any help is really appreciated!

Thanks

I would downgrade until you find a fix
