Description Dave Hyatt 2008-04-25 20:33:41 PDT 
When you transform a textfield, e.g., rotate it 10 degrees, you see horrible repaint problems.

(1) The caret doesn't blink properly.
(2) You see two focus rings, one offset from the other
(3) The contents don't always update right

Comment 5 Simon Fraser (smfr) 2008-11-06 18:15:03 PST 
Content updating is broken by LayoutState issues. When typing in a textarea, FrameView::layout() is laying out a subtree, in which case it pushes a LayoutState for the root (which is ignoring transforms). RenderBox::computeAbsoluteRepaintRect() then picks up that LayoutState and gets an offset that ignores transforms.
