Embedded swf and Firefox Scrolling issue on .aspx page

For Mozilla 1212813, it's Mozilla's bug, and they marked it WONTFIX.

Again, I'd really need to be able to debug it under a C++ debugger to understand why it's failing and either report it to Mozilla with a root-cause analysis, or get it fixed on our end.  I would not assume that just because issues described in bugs and forum posts sound similar to the issue that you're experience, that they have the same cause.

This *isn't* a widespread issue that I'm aware of, so it's interesting.  Given the behavior you're describing, it's probably a Firefox bug, but I don't have enough evidence to back that up.  It's also possible that there's a problem with your implementation (I find this reasonably unlikely) or maybe it's a GPU driver issue.

Without the ability to reproduce the issue we're just guessing, and that's not going to get anything resolved.

Sounds like a browser-related drawing bug.  It's hard to say without actually debugging it.  Nothing is jumping out at me from your snippet.

A URL that demonstrates the problem and some basics like Operating System and browser version would also be helpful.
