Since either the new release OR since you moved content to some sort of near-line storage, this is what I've seen:
1. Frequent crashes of the viewer (Macintosh, OS-X)
2. Frequent cases of the multicoloured spinning cursor going round and round and round and round and... To be honest, it does come back and let me continue about 1/2 the time.
3. Frequently (as in more than 75%) when I log in, one or more attachments are no longer attached. This is more often on the HUD items, but happens elsewhere too.
4. Huge triangular graphics suddenly appearing with one vertex at my avatar and the other vertices quite distant from me. This generally requires a quit and restart to cure... which then issue #3 rears its head again. Clearing cache seems to reduce the incidence of this.
5. Prims that are ordered to delete hanging around. Ditto for items in the contents of the prim.
6. Scripts simply not executing (although their status is set to run if you open them up) upon teleport. Often this is exhibited by AOs which simply stop running and can only be restarted by either removing them (which often the system refuses to do in this case) or quitting and restarting the client.
7. Postings to groups simply failing or (which is a better mode) simply taking inordinate times to be propagated.
8. Textures not loading or taking huge amounts of time to load upon teleporting - even if I teleport out from a sim, wait 2-3 minutes and then teleport back to where I started (I would think the textures would still be in cache).
9. A difficult to navigate bug reporting system, which makes it very difficult to report problems for those people that are either non-technophiles or simply have better things to do than spend an hour or two searching through your jira to see if a problem has been reported yet.
/me deletes a lot more so as to stick to data rather than lecture or venting...
