Isn't this the "datagrid scrolling" issue we just funded? The layout has groups inside a container group.

So - quick outline...

Set the layermode of the group to scrolling.

Make sure it is just a bare group - no scrollbars, no border.

Set the layermode of the other controls to static.

Set the acceleratedRendering of the stack to true.

Hopefully that should have some effect.

Warmest Regards,

Mark.

I have a stack/card that has:

(1) A background that is a high-res image,
(2) A group of about 200 groups that form a scrolling list,
(3) 2 buttons and another group all with transparencies that live on top of the scrolling list.

On a desktop computer, it’s fine. But on an actual device (or the simulator), the scrolling list scrolls REALLY sluggish. It’s slow, stutters and is absolutely unacceptable. I have messed around with the compositorType and the layerMode of objects -- all without seemingly any effect.

Is there a secret to getting a group on a complex card to scroll cleanly, or is LiveCode (8.1.5) unable to do this smoothly?

Any assistance would be greatly appreciated!
