Scrollbar "fade out" does not work

[ThomasH99]

Describe the bug I’m using the scrollbar but I cannot get it fade out smoothly/gradually, it just disappears abruptly.

The issue happened with a fadeout time of 1000 (1 second), but equally with 3000 (3s).

I don’t know if it’s important, but I also noticed that the scrollbar on the Simulator always stay visible, it only disappears on iOS and Android.

Here’s the code I call in init():

UIManager.getInstance().getLookAndFeel().setFadeScrollBar(true); UIManager.getInstance().getLookAndFeel().setFadeScrollBarSpeed(1000); //milliseconds I assume

and my CSS:

scrollVisibleBool: true; fadeScrollBarBool:true;

fadeScrollEdgeBool:false; /*not used I believe */ fadeScrollEdgeInt:0;

Scroll{ background: transparent; color:transparent; margin:0; padding: 0 0 0 0.5mm; }

ScrollThumb{ /*not used I believe */ cn1-derive:Scroll; color:transparent; padding: 0; margin:0; background: transparent; }

To Reproduce Add the code above to a Hello Word app's CSS and main.

Expected behavior The scrollbar should fade out gradually instead of disappear instantly after a short time.
