User Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/534.30 (KHTML, like Gecko) Chrome/12.0.742.112 Safari/534.30 Steps to reproduce: I have a web page with multiple overlapping absolutely positioned DIVs (referred to as "containers" below) each containing other DIVs and form elements. Some of these containers also hold <SELECT> tags. The <SELECT> tags do not have any additional event handlers defined. HTML and CSS have been verified using W3C validators. The behaviour was not seen in Firefox v3 Actual results: On clicking the <SELECT>, parts of the contents of the underlying containers appear on top of the display. What appears can be parts of words, parts of controls, odd words in a sentence, even just fractions of characters. This behaviour is prevented if I set the onmousedown event handler to a dummy event handler which prevents the default event action being taken. I can make the behaviour reoccur if I add a .focus() call. Expected results: Only the elements previously displayed should be displayed after clicking the <SELECT>

Could you attach a reduced Testcase shwoing th Issue by Chance? https://bugzilla.mozilla.org/attachment.cgi?bugid=669056&action=enter By "Firefox v3" you're speaking of Firefox 3.6.x Branch, yes?
I will try to produce a generic test case. I can confirm that I mean Firefox 3.6.x branch.

Does this happen if you turn off hardware acceleration in preferences and restart the browser?

Jamie, do you still have this problem? If so, can you please link to a page that shows it? I can help with making a reduced testcase if you can give me something to start with.
