As suggested in this thread https://forum.ubuntu- fr.org/viewtopic.php?id=1989216 installing gtk2-engines seems to solve the problem on that machine running U14.04 with intel core i7 haswell graphics and no proprietary graphic driver.
But on the other machine running U14.04 with nvidia graphics and proprietary drivers, where Firefox 46 runs fine, there is no gtk2-engines installed. Is this i7 Haswell specific ? How gtk2-engine may help ? I also confirm U16.04 is not affected (on the haswell one) but now has proprietary driver (microcode firmware for intel CPU's from Intel microcode) which is not proposed on U14.04 -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
