[Bug 1549455] Re: Unity8-dash on Intel Pineview graphics crashes and restarts continuously [qtubuntu: ASSERT: "eglDestroyContext(mEglDisplay, mEglContext) == EGL_TRUE"]
Those Mesa errors "Mesa: User error:" all look like OpenGL features that Unity8 is hitting but mir-demos don't. So those gl calls are also good candidates for explaining poor performance, especially if Mesa is falling back to software rendering for them. Unfortunately we're covering multiple issues here. This bug should be about the dash crashing continuously. We can deal with performance elsewhere... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1549455 Title: Unity8-dash on Intel Pineview graphics crashes and restarts continuously [qtubuntu: ASSERT: "eglDestroyContext(mEglDisplay, mEglContext) == EGL_TRUE"] To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1549455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

P.S. In my experience, confusing GL and GLES is something Mesa actually does well. It provides a single API for both of them and even lets you accidentally use GL features in GLES that should not exist. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1549455 Title: Unity8-dash on Intel Pineview graphics crashes and restarts continuously [qtubuntu: ASSERT: "eglDestroyContext(mEglDisplay, mEglContext) == EGL_TRUE"] To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1549455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Albert was able to reproduce this on his netbook. The dash issues we suspect are due to: https://bugs.launchpad.net/qtubuntu/+bug/1580124 https://bugs.launchpad.net/qtubuntu/+bug/1580118 I suspect also that the poor unity8 performance is due to a GL/GLES mismatch in unity8. Running unity8 with MESA_DEBUG=1 EGL_LOG_LEVEL=debug reveals a few MESA errors: http://paste.ubuntu.com/16344427/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1549455 Title: Unity8-dash on Intel Pineview graphics crashes and restarts continuously [qtubuntu: ASSERT: "eglDestroyContext(mEglDisplay, mEglContext) == EGL_TRUE"] To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1549455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Loïc: Our findings appear to be identical. Basic rendering on Pineview (including shaders) is fast and smooth till I used trig functions in shaders (mir_demo_client_eglplasma). I doubt Unity/Ubuntu toolkit uses much trig, but it probably hits some similarly expensive functions. Expensive functions aren't the problem with the dash though. The dash never starts so that may be non-existent functions instead. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1549455 Title: Unity8-dash on Intel Pineview graphics crashes and restarts continuously [qtubuntu: ASSERT: "eglDestroyContext(mEglDisplay, mEglContext) == EGL_TRUE"] To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1549455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Not related to the assertion but I got a Netbook with such a chip and it was easily falling back to slow GPU/driver pathes. I remember for instance transcendental functions in pixel shaders (sin, cos, etc) taking ~1 sec to complete. So we could be hitting such an issue. Last time I checked QtQuick didn't use trigo though (except in visualisation debug modes). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1549455 Title: Unity8-dash on Intel Pineview graphics crashes and restarts continuously [qtubuntu: ASSERT: "eglDestroyContext(mEglDisplay, mEglContext) == EGL_TRUE"] To manage notifications about this bug go to: https://bugs.launchpad.net/mir/+bug/1549455/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
