I'm playing, at the moment, on a Mac running Chrome.
The game is the slowest/laggiest I've ever seen it -- so slow that I can't even type in the chat window. I am also getting repeated "This page has become unresponsive: kill or wait" error pop-ups whenever I have the game world up in a tab. Usually, this error includes ALL Glitch tabs in the listing. Doing things like opening a forum tab from the drop-down menu in game takes about 45 seconds to complete, and sometimes the game tab cannot be closed (presumably due to this slow-down). However, the game has NOT crashed. Just grinds everything to a halt. This happens both in a "regular" tab with my usual extensions running, in a regular tab with extensions disabled, and in an incognito window with NO extensions at all.
Are others experiencing this with Chrome on Macs? I'm curious to see how it plays tonight on my Windows machine (also with Chrome).
