This just started today. When I type in the product description editor my screen jumps after every character I type. Imagine the text moving down a line and then back up to its original position after every character is typed.
I traced it to the title, it seems related to how long the product title is. Over a certain length this jumping occurs. Under whatever this length is, there is NO jumping.
Is anyone else seeing this? It's highly annoying, I can't input product data like this.
