The relevence of whether it is captured in a screenshot is that it gives a clue as to whereabout in the driver it fails - or rather it rules out several potential candidates. A GPU hang will indeed be first noticed by a stutter and be recorded in the kernel log - on your system, it should not require a reboot except in exceptional circumstances.
Not sure about the libreoffice glitch, that I would say is more likely to be a gui issue rather than driver, but you already have too many weirds things happening that one more wouldn't surprise me. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1157458 Title: visual glitch To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1157458/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
