Maybe it's my drivers, but I've been here since August and have never seen this problem until today.
There's one type of tree that mostly doesn't display correctly. Occasionally, I can see it, but mostly only a few bands on the trunk are visible. I can still select and edit it, but I can't see it. It's happening with trees that have been in world for at least a couple of months as well as newly rezzed trees.
Anyone else seen this? I reported it to LL, but just wondering if anyone else has seen this.
