Hello, I confirm this bug also affects me on several Kubuntu 16.04 machines since this morning, apparently following the unattended upgrades that happened on Friday.
The symptoms are as described int the bugerport. I see them in okular and a custom Python application that uses PyQt4. The bug makes these applications unusable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1780664 Title: Recent libgl-mesa graphics update prevents drop down list menu appearing in apps like firefox three line/bar menu icon To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1780664/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
