SpriteSequence crashes on iOS if QtQuick.Particles is imported


    • Type: Bug

    • Labels:
    • Environment:
      Host: Mac OS 10.12.6

      Tested Qt versions: 5.8.0, 5.9.0, 5.9.1, 5.9.2
    • Platform/s:


      Displaying a SpriteSequence crashes the app on iOS, but only if QtQuick.Particles 2.0 is imported.

      This is a regression as the problem definitely did not occur Qt 5.4. 

      The crash seems to happen when the QML import scanner imports the library libparticlesplugin.prl (full path: /5.9/ios/qml/QtQuick/Particles.2/libparticlesplugin.prl).

      Crash happens in QSGBatchRenderer::ShaderManager::prepareMaterial (qsgbatchrenderer.cpp line 150).

      Minimal example:

      • Removing the line "import QtQuick.Particles" makes it work without crashing
      • Image used is Qt logo from http://brand.qt.io/downloads/ (though it crashes with any image)

      import QtQuick 2.8
      import QtQuick.Window 2.2
      import QtQuick.Particles 2.0

      Window {
      visible: true
      width: 640
      height: 480

      SpriteSequence {
      width: 128
      height: 128
      anchors.centerIn: parent
      goalSprite: "test"

      Sprite {

      name: "test"
      frameWidth: 128
      frameHeight: 128
      frameCount: 1
