I've noticed there are several problems that seem to be on the client end that might have something to do with the game loop/rendering routine
1) attachments that you put on or remove not showing up. Biggest culprit is going from one custom avatar to another. Think this is client side only as problem can be fixed by relogging (since I gather this refreshes the draw state or video buffer).
2) Objects stil remain (at least drawn by client) after you delete them. Again this can be fixed by relogging but is a pain.
3) The last one I suspect may not be client end or just basic lag. Contents of objects have gotten really slow after the recent patch. Any updates to the contents i.e. adding a script or inventory object takes forever to update if at all. Sometimes you can force it to update a bit quicker if you drag the same item in again forcing it to refresh with the duplicate status (from renaming?) This gets especially annoying when workign with scripts when you cant even see the script running to even open it to make changes
