IMX6 - Failure to match EGLConfig and X Visual buffer depth crashes app

Reference QTBUG-9444

There seems to be lot of good background on the reasoning of why Qt currently performs as it does, but the current implementation requires a hack patch to be applied for all IMX6 users to get OpenGL functionality.

I patched src/platformsupport/eglconvenience/qxlibeglintegration.cpp
in VisualID QXlibEglIntegration::getCompatibleVisualId(Display *display, EGLDisplay
to return

• return (VisualID)0;
  + return (VisualID)33;

I have a slightly different setup from most people using imx6, as I bootstrapped Debian/Jessie and then built Xorg from scratch and then subsequently Qt5. Qt5 from apt-get would have been fine if it were not for this bug preventing OpenGL functionality.

I will report with Freescale and hope they take up the issue with Vivante, but I hold little hope there. A little googling and digging into yocto builds will notice that the patch is pretty common practice for imx6 users. https://lists.yoctoproject.org/pipermail/meta-freescale/2013-September/004617.html
