Problems and Fixes

This is a collection of known problems, and hopfully their fixes.

  • QtQuick could perform badly or not at all on systems without decent OpenGL driver. This is also true through X11 remote session or Windows remote desktop. For Qt 5.7 and above, the workaround is to use software render.
    $ export QMLSCENE_DEVICE=softwarecontext

    For Qt 5.6, this software render plugin has to be installed manually.

    $ git clone https://github.com/qt/qtdeclarative-render2d.git
    $ cd qtdeclarative-render2d
    $ git checkout 5.6.0
    $ qmake
    $ [sudo] make install
