QML Flickable Element performance

[cadlg]

Hello.

I've been experimenting with the QML's flickable element, but when running applications on a Symbian^1 device (5230) I get a very poor performance. Even a single text element with no more than 15 lines of text scrolls like if there were too much friction.

I have tried varying the flickDeceleration and maximumFlickVelocity properties but it has not made any difference.

The app is going to run on Symbian^3, but I don't have a S^3 device to test, and have these questions:

-Is there something I can do to improve performance on Symbian^1 ?
-Can somebody confirm if this performance issue exists on Symbian^3 devices ?

I'm loading QML using QDeclarativeView.

Any help or comment greatly appreciated.

The reason for the poor performance was that the flickable element was declared over a rectangle with an opacity different than 1 (the default). If the opacity specification is removed from the background rectangle, the flickable element performs well. This only affects performance when in portrait mode.

I guess Symbian^3 devices don't suffer from this.
