User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:17.0) Gecko/20100101 Firefox/17.0 Build ID: 20121128204232 Steps to reproduce: Right-clicked on anything inside of firefox browser, no addons installed. Win7 Pro X64 Actual results: On mouse movement, the menu disappears, making the website below visible. Moving the mouse further, the menu shortly flickers, but mostly remains invisible. The menu items still work, when clicking on them if you know where clicking on the correct spot. Does not happen all the time (but very often), and even an invisible or flickering menu may settle back to normal. Expected results: Normal Menu Behavior, no disappearing.
Devon: Please open about:support (enter as URL in Firefox) and post the graphic section (but please not everything) in this bug. After that disable the hardware acceleration in options/advanced/general (FF restart required) and try it the issue disappears.
Are you using 2 monitors? If yes, does this issue happen on the 2ndary monitor?
It's passed a long time without having more info about this. I'll close this for now please reopen if you consider it is still valid or you can add more info to reproduce it.
