Confirmed, same thing happening in a Thinkpad T440p, intel i7-4800MQ. Today I upgraded Firefox and immediately afterwards, the browser started showing similar glitches. I have rebooted the computer and the problems are still here, making usage of Firefox very annoying.
I'm using Ubuntu 14.04 with Gnome environment. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1576382 Title: Firefox 46 → display glitch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1576382/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
