You can write them both up at bugreports.qt.io.  Be sure to provide an example.  SVG animation is pretty rarely used AFAIK… I don’t remember hearing of anybody using it before, so it’s not surprising if there are bugs.  You can also write a patch if you know what to do about it, and submit it to codereview.qt-project.org

To stop and restart it I found a hack - disconnect this signal and reload SVG image. In Windows and Linux this stops animation. Stupid but working. But now I use this widget for project on Andriod (using QML is not the way, QML is too weak and lame for me). But I cannot stop SVG animation on Android. It runs always. It does not depend from any connections, framerate, reloading, so on. Of course I can use another hack - to stop animation I can load non-animated image and to start I can load animated again.
