This is a bug in the Intel Mesa driver. Unfortunately I have little hope that it will be fixed soon: "This suggests that we're missing a flush somewhere... but finding where is like finding a needle in all the haystacks. :(" (https://bugs.freedesktop.org/show_bug.cgi?id=80568)
Anyways, as far as Ubuntu is concerned this seems to be the same as bug 1382673, bug 1385810 and bug 1394424. ** Bug watch added: freedesktop.org Bugzilla #80568 https://bugs.freedesktop.org/show_bug.cgi?id=80568 ** Also affects: xorg-server via https://bugs.freedesktop.org/show_bug.cgi?id=80568 Importance: Unknown Status: Unknown ** Project changed: xorg-server => mesa -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1388612 Title: [GM965] GPU lockup running OpenGL applications on Dell Vostro 1510 To manage notifications about this bug go to: https://bugs.launchpad.net/mesa/+bug/1388612/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
