 --> (https://bugs.webkit.org/attachment.cgi?id=63053)
Chromium Nightly build

When background-size property is used, the background image moves, and the rendering is slow. Especially with move or dragdrop operation.

I created a sample page, and I put in attachments screenshots of chromium with a recent webkit and midori with a old webkit.

This bug has been verified with Chromium stable, Chromium nightly build, Safari stable, Safari nightly build, and Qt Webkit.

According to tests, it would appear between version WebKit/531.2 (Midori) and AppleWebKit/532.4 version (Safari).
