I have experienced an odd effect when viewing some (system?) avatars when the view intersects with sky. I have added an image to illustrate the phenomenon. *Toggling the new Render Invisiprims doesn't seem to be related.

Darn...

Yet, this is indeed the invisprim code change that introduced this bug... There are two bugs actually:
The first is due to the (inappropriate) simplification I did by calling LLDrawPoolInvisible::render() from LLDrawPoolInvisible::renderDeferred(), because I did not notice the gGL.setColorMask(true, true) in the latter (instead of false in the former). The second bug is that gGL.setColorMask(true, true) must still be called from LLDrawPoolInvisible::renderDeferred() whenever insiprims rendering is disabled...

I'm going to publish a fixed version later today since it also affects other stuff than just legacy avatars in a sky background...

Thanks for the new version. I have verified that I no longer see that behavior.
