Hi, It's me again. If I zoom in or out at those non-drawn rectangles, the draw will occur. Note that codes that create these features have been executed right after the page loads.
Thanks.

When I pan the map, the features that now go in the viewport are not always get drawn. If I click on the vector layer Select item in the switcher control, then they are drawn after clicking on the switcher. 1. What could cause the problem of no-drawing? 2. I noticed noticeable performance latency. Any idea how to improve or how to design when dealing with thousands (could be tens of thousands) of markers/polygons? Thanks for your help. JK
