Note it is only Unity8 which is mixing GL and GLES calls, clients are not doing that. Qt clients are only doing GL calls on desktop.
Nothing obvious comes to mind here. It may be Qt's EGL configuration code is failing - code that QtUbuntu is using. Another consumer of that same code is the EGL backend for the XCB QPA plugin - the non-default - as usually the GLX backend is used. Could someone with a problematic system log into Unity7, and for a simple qml file, run: QT_XCB_GL_INTEGRATION=xcb_egl qmlscene ~/test.qml and see does it fail? -- You received this bug notification because you are a member of Desktop 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/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
