[Bug 1620934] Re: Qt/QML apps don't render any more (logs say "QEGLPlatformContext: eglMakeCurrent failed: 3001")

2016-09-13 Thread Timo Aaltonen 
Without this, if a configuration is, say, available only on GLES2/3, but
not on GLES1, and is rejected by the dri module's bindContext call,
eglMakeCurrent fails with error "EGL_SUCCESS".

In this patch, we set error to EGL_BAD_MATCH, which is what CTS/dEQP
dEQP-EGL.functional.surfaceless_context expect.

2016-09-13 Thread Gerry Boland 
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?

Maybe... Mesa only just started to care about mixing and matching GL
with GLES in invalid ways. I know we have done it in the past and
possibly still do. Maybe today is the day Mesa finally started checking
the validity of our GL calls...?

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.

2016-09-12 Thread Daniel van Vugt 
Another prime candidate that possibly triggered this bug:
   https://launchpad.net/ubuntu/+source/mesa/12.0.2-1ubuntu1
Released on 7 September (which would have been 8 Sept here).

It could easily be that our Qt apps are (and always have been)
requesting some EGL attributes that Mesa can not or should not provide.
That could be a Mesa bug or a Qt bug that's been around for much longer
and Mesa only just became pedantic enough to say no. Remember EGL
clients from the 'mir-demos' package still render OK so this is
something specific to Q* clients.

This only happens in yakkety. The same qtmir, qtubuntu and unity8 runs
fine in xenial. Lost a couple of hours on this issue yesterday and my

The only relevant piece there seems to be qtmir, but looking at its
changelog [1] there's no related changes there...
