Settings "QSG_INFO=1", you get: qt.scenegraph.info: texture atlas dimensions: 2048x2048 qt.scenegraph.info: R/G/B/A Buffers: 8 8 8 0 qt.scenegraph.info: Depth Buffer: 24 qt.scenegraph.info: Stencil Buffer: 8 qt.scenegraph.info: Samples: -1 qt.scenegraph.info: GL_VENDOR: Qualcomm qt.scenegraph.info: GL_RENDERER: Adreno (TM) 320 qt.scenegraph.info: GL_VERSION: OpenGL ES 3.0 V@53.0 AU@ (CL@) the A Buffer should be 8. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1502093 Title: unity8 crash on mako rc-proposed/ubuntu with latest unity8/mir/powerd To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-devices-system-image/+bug/1502093/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
