At the above URL scroll to the "Alpaca Quiz" flash animation at the bottom of the page. Note how the animation draws a custom pointer underneath the mouse pointer and other mouseover effects work fine. Zoom the page in or out. The flash based content is visually drawn correctly. However note how the mouse pointer and mouseover effects do not work correctly now. It seems like the wrong co-ordinates are being passed through as Flash thinks the pointer is in a different place. Note that I have only tested this using Safari 4.0 on Windows XP using Adobe Flash version 10.0.22.87.

Very important bug, (poor) workaround made for Chrome on Mac (http://code.google.com/p/chromium/issues/detail?id=26466), Chrome for Windows still very much affected. See http://code.google.com/p/chromium/issues/detail?id=9996 for more details.

Bug 42987 fixes this.
Bug 42987 fixes this only for Chromium; the original bug was filed about Safari.
Is this still broken in nightlies? Could have been fixed in bug 74209.
This is working okay on Safari 5.1.3 on Lion when zooming in/out using Command+/-. However if I try zooming using pinch gesture instead, things are not so good. The flash content either disappears or no longer accepts mouse over. Doing a zoom in/out using the Command key/menu option fixes this. That is probably a different bug?
Yes, that sounds like a different bug. Could you please test with a nightly build from <http://nightly.webkit.org>? These are very easy and safe to use, as they don't permanently install or change anything on your system.
WebKit no longer supports NSAPI plugins.
