Running Ubuntu 14.04 after the last update I have this strange issue where the button menu doesn't show their content after clicking they get stuck in as "select state" and button menu doesn't show up. Also, some website while show up a static rectangle on the middle-left like if a notification window isn't showing up properly. This issue is with all the profiles, tried to remove all addons didn't work, try to disable acceleration didn't work try to refresh didn't work. Running in safe mode the problem doesn't show up. I reset my .mozilla firefox problem still show up... so it doesn't seem to be addons/profile related but I out of idea... I tried uploading an screenshot but I'm getting and ever turning circue icon and Upload "filename" ... test that never change to a different status. Thank you. Thanks
