First off, i'd like to point out that i do not know how to recreate this bug. All i can say is that having low frame rates, and swapping Second Life in and out of the Swap File tends to cause this bug.
In a straight forward sence, no-matter where i look verticies of nearby drawn objects are /pulled/ to the center of my screen. I do admit that this doesn't happen to every object, and effected objects don't always pull into my screen, but into eachother.
Not often, but it has occured, verticies from objects attached to my avatar pull away into the world, not into my screen.
My personal opinion as a 3D graphics designer, the rendering system for computing verticies needs optimizing, since they are verticies that are being pulled, and this is obvious by the triangular shape, and the streching of the mapping. Once this occurs, you cannot get rid of it without restarting the Second Life Viewer Client.
This HAS occured with previous Windlight, and Release Candidate viewers, and to my last memory, started occuring around December, so whatever version was released then.
For a detailed explination, a picture says 1,000 words, see the attachment.
Again, i do not know how to recreate this, but i have noticed that i am not alone. Others who have told me they got it, said they fixed it with a driver update, however i can't complete this as i have the latest drivers and reinstalling them does nothing.

Corrupted Verticies
VWR-7038. The image posted by Zion Tristan here is EXACTLY the effect I see.The Windlight enhancement started causing objects in my environment to tear or smear, as shown in the attached images. It is as if a prim creates a 'light ray' artifact that slants away from the origin Prim until the effect is terminated by an occluding object or the ground. The light rays appear to be torn/smeared textures of the origin prim.
This effect started with the Windlight non-production (beta or release candidate, i forget the terminology) test client viewers. Now that the Windlight enhancement is part of the production client viewer, Certain hardware configurations cannot ever login without this effect appearing at some time during my SL session.
This effect is not always visible; pivoting the avatar viewpoint a few degrees horizontally or vertically often makes the artifacting effect disappear. However, the artifacting is not always visible from the same point of view. i can turn 360 and have the effect disappear at an angle previously visible, or appear when previously invisible.
This effect is most evident when the atmospheric shaders are enabled. However, disabling atmospheric shaders is not invariably successful in suppressing the artifacting.
This effect is visible through many Windlight client viewer updates, through 1.19.x and 1.20.x RC.
This effect is visible through many graphics driver updates.
This effect is visible using Windows XP Pro (SP2 as well as no SP) as well as Windows Vista OS (no SP).
This effect is visible using NVIDIA as well as ATI graphics hardware.
Example configurations with this issue:
Note: Multiple NVIDIA and ATI GPU configurations not described here are performing as expected: without this artifacting effect. There are 14 separate machines in this environment; only the three detailed above display the artifacting effect.
