Hi! Could you please send us a screenshot so we can take a look at the issue?

What do you mean by "screen tearing?"

Lots of lag during calls to a server too; e.g. changing rooms, upgrading artifacts etc.  It is positively crawling at times.  This since the last patch...

Same issue here on PlariumPlay on MacBook.  Basically unplayable.

Can you post screenshots?

I tried taking screenshots but I am unable to capture it in time.

@Loma screen tearing is when lines appear, either horizontally or vertically, on the screen. A simple Google search will illustrate what I'm talking about.

Screen shot couldn't do it.  I could try to do a vid, but basically in a fight, one toon starts to attack, screen freezes, a minute or two later, a different toon is attacking and 2 opponents and one ally are already dead.

A video would be great! Please submit/post if you can. :)
