Tile boundaries visible at certain zoom levels

[pmjobin]

I built the demo app using Flutter 2.8.1 (desktop linux target) and I noticed that tile boundaries pop out as white lines at certain zoom levels while they are seamless at others.

Same issue, and this issue only happens on Flutter 2.8.x and above..

But this problem depends on rotation disable
If I run a demo project from the repo, with disabled zoom (~InteractiveFlag.rotate)

FlutterMap( options: MapOptions( center: LatLng(51.5, -0.09), interactiveFlags: InteractiveFlag.all & ~InteractiveFlag.rotate, zoom: 5.0, )

I see white lines

There isn't any problem if the rotation is enabled

Does this happen on mobile too, or just on desktop ?

On mobile too, but only with disabled rotation (by interactiveFlags or nonRotatedLayers)

This seems strange, and would be probably Flutter 2.8's fault, because I haven't seen this before.
Maybe the changelog will hold the answers?

I think that located problem, if I delete Opacity widget in _AnimatedTileState

Before:

return Opacity( opacity: widget.tile.opacity, child: widget.tileBuilder == null ? tileWidget : widget.tileBuilder!(context, tileWidget, widget.tile), );

After:

return widget.tileBuilder == null ? tileWidget : widget.tileBuilder!(context, tileWidget, widget.tile);

The problem is gone. There are no white lines.

And there are many opacity issues that were merged in [release notes](https://docs.flutter.dev/development/tools/sdk/release-notes/release-notes-2.8.
