When a edit box is focussed to get the keyboard focus, Safari gets a WM_PAINT for every cursor_blink

Use SPY++ that comes with Visual studio to see the messages posted on "WebView" window.

GDI should take care of re-painting what was behind the cursor. There should not be WM_PAINT messages.

Compare with Firefox and IE to see the difference

WebKit on Windows uses CoreGraphics to draw, not GDI. This includes drawing the blinking cursor/caret. (The painting that we do for the caret is limited to the area of the caret itself, and is very fast)
