Text editor issues in Chrome (webkit)

I have actually switched to chrome as primary browser. I have lots of problems with the font rendering of these text boxes though. Only place I have had any problems. Whenever I move the cursor or make newlines and such the changes isn't visually applied but they are there. If I move the cursor back over the "outdated" characters they update to reflect whats actually there..

It's kinda like when a window in windows freezes and you can paint with it. Works fine in firefox though so I assume the problem is related to webkit.

Also, in chrome my signature is always placed in these boxes before I start to type and I have to make a few newlines to get rid of it first.

Weirdness.
