Created attachment 8541384 [details] Faux Buttons.gif User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:37.0) Gecko/20100101 Firefox/37.0 Build ID: 20141219030202 Steps to reproduce: No way to reproduce Actual results: It's happened rarely that for a window the minimize/maximize/close window controls will disappear and in their place is a black square. If I hover over the black square different nonfunctional window controls will appear, similar to the buttons one might see with window scheme Basic. I have attached an animated gif showing what happens when I hover over. Other windows and new windows appear to function normally. I have Aero enabled and the window control buttons I normally see in Nightly windows are the correct Aero ones.

Do you use a special theme for Firefox? Could you try to update your drivers to the latest version (18.104.22.168.3517)?

I'm using "Google Chrome 4 Firefox" right now: https://addons.mozilla.org/en-us/firefox/addon/google-chrome-4-firefox/ I'll probably leave the drivers as is. I don't have this problem with any other program.
Remove/change the theme, it should be fixed.
