Blue cones hovering on moving objects

Starting one or two deays after the update, I have a weird problem: moving objects come with blue cones hovering over them or drifting behind them. Not all objects, though, only some; I haven't been able to figure out the rationale between properly rendered objects and blue-coned objects. In clubs, avatars moving have a tail of cones behind them. Sometimes the cones will gradualy disappear and then the moving objects are finally properly visible. If it helps, I can post a few snapshots.

It severly hampers the viual pleasure of SL. Any ideas on how I might solve this, and whether this problem is update-related? N.B.: I haven't changed any of the SL-settings, not those of my Powerbook (runing MacOs 10.4.5).

Yikes. I had searched this forum extensively and hadn't found anybdy else with this problem. Only after posting this, uI stumbled on the SL wiki, and thre was my answer:

Swithcing off 'show updates' under the Debug menu did it. Yay, my joy is restored!

Hi Karin, and others, I saw this just now and was about to post the answer when I saw Karin had found it.

This is one of the things that Live Help (which I'm not always a huge fan of), asking any of the Mac groups (although it's not specifically a mac issue, it's an interface issue) and some of the other 'helper' groups (Mentors, Secret's Helping Hands, Teazers, etc.) would be worth a try before coming over here. If you'd happened to catch me on I'd have been able to answer the question as soon as I saw the title I knew and I suspect a number of others would have known too!

For the sake of complete information there are several different colours of cones - it's been a while, but I think blue are partial updates and red are full updates, purple occur when you get a partial and then a full update (and want to throttle the scripter). Prims which are updating *tend* to be heavier on the sim than most other things because the sim is redrawing them or drawing them somewhere else (as in your example). It's possible to write really laggy scripts on non-updating prims too, so it's not 100% guaranteed, but it's another moderately useful tool in a laggy sim.
