[OpenLayers-Dev] addOptions and redraw

[Bart van den Eijnden]

Hey Eric,

right, what I am doing now is calling display in the following way:

layer.display(layer.calculateInRange());

but it feels a bit weird to do it this way.

With out of sync I mean indeed being displaced, so that's similar to what your github issue describes. Thanks for the pointer I'll check that out.

Best regards,
Bart
