<div dir="ltr">Andreas, thanks for that, will do. That doesn't fix the other issue, though, which is that zooming in and out causes the layers to "drift" physically. An object that is on the west side of the street at one zoom level will overlap the street at the next zoom level in or out, and so forth. The rendering only appears to be accurate at the initial zoom level. I haven't tested this extensively for WMS layers, but the problem is consistent with vector layers.<div>
<br></div><div style>This is a recent change - I've been using OpenLayers for three years now, and I saw this problem back in 2.11 for a time and the fix was to add a maxExtent to the map. That fix no longer works now, and I'm at a loss as to what to fix. </div>
