AnimatedSprite source change causes infinite loop in QQuickSpriteEngine::assembledImage()

    • b61c774ce58d15bfc26a2a75b55e3f5eefbcdcc2

      Steps to reproduce the issue:

      • Extract the attached file (animatedSpriteInfiniteLoop.zip) and run it with "qmlscene animatedSpriteInfiniteLoop.qml"
      • Click on it.

      Outcome:
      The process enters into an infinited loop inside QQuickSpriteEngine::assembledImage(). More speficically inside "while (framesLeft > 0)

      {...}

      " as framesLeft is never decremented because "copied/frameWidth" in the expression "framesLeft -= copied/frameWidth;" always resolves to zero because copied < frameWidth.

      Comments:
      Got a simple fix in the works.
