Purge direct OpenGL code path in Qt Quick

    XMLWordPrintable

    Details

      Description

      Direct OpenGL usage is to be removed, together with the QSG_RHI environment variable. From that point on the default behavior will be as if one ran with QSG_RHI=1.

      This may present breakages on all levels, in Quick itself, in examples, in tests, in other modules, documentation will become invalid, etc.
