Crash when using QtQuick Canvas

    XMLWordPrintable

    Details

      Description

      1. apply the attached patch to qtcreator to make it use the Canvas included in QtQuick instead of its own. Note that it only changes QML code, not C++.
      2. Start qtcreator and switch to QML debugger.
      3. crash from somewhere deep in the QML engine:
