Screenshot of display problem when clicking about button

When filters are used on text elements it causes a display problem when the set visibility attribute function is called. The elements with filters applied are not hidden and are left visible throughout the presentation. This problem can be seen in the following file.

The problem relates to filter usage I believe because, if you use a webkit browser that does not support filters like Apple Safari 5.0.3, the problem does not occur. It should be noted that elements with filters that are not set to be hidden work just fine.

Webkit: Version 5.0.3 (6533.19.4, r87026)

Platform: Mac OSX 10.6.4 (Snow Leopard)

Included are two screenshots reflecting the problem. One is with nightly build of webkit, the other using Safari 5.0.3. Both show what happens when the About button is clicked setting the hide visibility attribute in motion.
