Created attachment 352365 [details] screenshot To reproduce: - Make sure you have a certain minimum amount of bookmarks (otherwise the bug doesn't occur for some reason). - Right-click some bookmark to open the context menu. Make sure the 'Paste' menu-item is disabled (by not having a bookmark item in your clipboard). - Hover over the 'Paste' menu-item. Result: Quite often, that disabled menu-item is not highlighted and gets highlighted only sporadically, while moving the mouse. This is a behavior similar as described in bug 306149. I seem to get a regression range between 2008-10-09 and 2008-10-10: http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2008-10-09+03%3A00%3A00&enddate=2008-10-10+05%3A00%3A00 So this seems to me a regression somehow from bug 69710 somehow, since that one added text-shadow: 1px 1px ThreeDHighlight; css to menu-items. But that's probably not the fundamental cause of this bug.
This is as same as Bug 492960 - It flickers when I move a mouse on an disabled context menuitem of pull down Bookmarks menu
I face same issue as well. (Hover blink in context menu of bookmarks popup) but, not only on disabled menu item, it happend on all menu items. Step to reproduce: 1) Open and website got marquee running text. 2) Then right click any bookmark to bring out context menu of bookmarks popup. Result: Same as Martijn Wargers mentioned in first post.
addional information: - my case only happen while website in current tab contains marquee content. - If the marquee website is at background tab, the problem won't occur.
just realize it is open bugs since 2008. no body to fix this bug?
