CONFIRMED. Downgrading Mesa to 12.0.1 fixes the problem: https://launchpad.net/ubuntu/+source/mesa/12.0.1-3ubuntu2/+build/10506751
So the regression was triggered by: https://launchpad.net/ubuntu/+source/mesa/12.0.2-1ubuntu1 However that doesn't mean Mesa is buggy necessarily. Our Qt EGL setup code might be requesting something invalid and it only just became a fatal error. In that case our Qt code would need fixing rather than Mesa. Indeed non-Qt clients don't have the bug at all. ** Changed in: mesa (Ubuntu) Status: Invalid => Confirmed ** Changed in: mesa (Ubuntu) Importance: Undecided => Critical -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/1620934 Title: Qt/QML apps don't render any more (logs say "QEGLPlatformContext: eglMakeCurrent failed: 3001") Status in Canonical System Image: Confirmed Status in Mir: Invalid Status in QtMir: Confirmed Status in qtubuntu: Confirmed Status in mesa package in Ubuntu: Confirmed Status in qtmir package in Ubuntu: Confirmed Status in qtubuntu package in Ubuntu: Confirmed Status in unity8 package in Ubuntu: Invalid Bug description: nothing works, all apps, dash are just black windows - Ubuntu 16.10 + proposed (x86, and using Nvidia 8600GT with nouveau drivers) and they fail with this error "QEGLPlatformContext: eglMakeCurrent failed: 3001" To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1620934/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
