When you change the playbackrate of a MediaPlayer instance, the current position will change randomly. For example it will jump back 1 or 2 seconds as soon as you change the playback rate, instead of keeping the position.

Attached is a minimal reproducable example as zip file.

Column {
		anchors.fill: parent
		MediaPlayer {
			id: mediaPlayer
			autoPlay: true
			source: "https://download.blender.org/peach/bigbuckbunny_movies/big_buck_bunny_480p_stereo.ogg"
			playbackRate: playbackSpeed.currentValue
			notifyInterval: 32
		}
		VideoOutput {
			source: mediaPlayer
			Slider {
				anchors { bottom: parent.bottom; left: parent.left; right: parent.right }
				to: mediaPlayer.duration
				value: mediaPlayer.position
				onMoved: mediaPlayer.seek(position * to);
			}
		}
		Label {
			text: "Time: " + mediaPlayer.position + " ms"
		}
		ComboBox {
			id: playbackSpeed
			model: [0.5, 0.75, 1, 1.25, 1.5, 1.75, 2]
			currentIndex: 2
			displayText: currentText + "x"
			implicitWidth: 64
		}
