 Description  « Hide
Since updating my ATI Catalyst graphics drivers from v9.3 to v9.4, I have experienced extreme graphical corruption of all avatar attachments, mine and others. After checking through the preferences I have found this is only occuring when the VBO is turned on, and stops as soon as I turn it off. See attached screen shot.

To recreate this problem, on a Sapphire ATI Radeon HD 4850 using Catalyst Drivers V9.4:

Attach some attachments to the avatar, and turn on the OpenGL VBO. You may needc to move and zoom the camera around a bit before the corruption occurs.

I did not seem to have this problem on the v9.3 catalyst drivers, so I don't know if its a SL problem or something ATI did when updating the drivers.

Fortunately I can work around this by just turning the VBO off for now.
