Firefox and Google Chrome browser pop-ups 80% of the time not showing window title bar in Ubuntu 14.04. If you increase the window size the title bar appears. Also the indicator in the launcher icon does not show the window as open until you click on the launcher icon.
I have reproduce this on Nvidia and Intel graphics hardware using both open and close source drivers. I have not tried it on ati graphics yet
I believe that it is Compiz not sizing the windows correctly causing the problem.
does anyone know a fix to this? It gets really annoying with website with lots of pop-ups.
