    Hi, I'm trying to execute the Qt3D simple-cpp application on imx6. But I get the error QOpenGLShader::link: LinkShaders: Too many instructions.

    Compilation goes fine, execution also starts but I can't see anything on the screen.
    Has someone get this kind of error? I can't find information on google..
    I'm using Qt 5.9.6 and for the example I have selected this revision.

    Thanks in advance!

      Hi
      It does sound like this
      https://bugreports.qt.io/browse/QTBUG-59349
      you could try adding environment var
      QT3D_GLSL100_WORKAROUND
      and see if that makes any difference.

        Can you run other examples in your imx6? What setup are you using?

        A lot has been changed in Qt3D since version Qt 5.9.6. Is there a specific reason not to use the latest version?

              @eddy I'm using what som provider offers (toradex) and Qt comes in this version.
              Maybe it's a good solution use the latest LTS QT, i think is 5.12.. but by now we don't have time to switch to..

              Thanks!
