I think that's a result of the server lag though, not actual client instability... Like Flash is trash in general, but if I play iClassic in a browser dedicated only to iClassic with no extensions and everything turned down or off, I pretty much never freeze or anything
The Graal client ran super smooth to me up until Graal6, I think

Things like halloween fog, rain, and other effects make Graal on PC super slow, especially when on full screen. If you try to use 100% zoom (default), and go into full-screen, load friends, their profile, you will see that the game and players in the background start moving super slowly. If you zoom in at 200%, it won't be as slow, but it's definitely still noticeable, compared to just not entering full-screen.
If you use an ipad air 2 and up, super smooth, with the occasional 2 second freezes, after not reinstalling the game for a while. None of the effects slow it down, not even if you zoom out.
