Hi, I don't have a lot of experience with OpenLayers and am trying to fix a few problems in an application. The application has to run in a JavaFX WebView over the integration/development of which I have no control. The application is supposed to display some text values on the map updated every second and is expected to stay open for days if not weeks. I have come across the following problems:
1. Zoom and pan makes the Java process memory rise (also happens if the map is opened in other browsers: the browser's memory rises). I reported this and was pointed to this issue <http://github.com/openlayers/openlayers/issues/1155> . What this says is that a fix in 2.13 causes the browser to cache the image and the browser should be able to handle its memory. However, I have found that browser memory rises to a point where it crashes if the zooming and panning is quick enough. I tried reverting the changeset mentioned in the issue 1155 thread and setting tileManager to null but it didn't make much difference. I reverted to 2.12 and it solved the memory rise problem but produced the second problem below. 2. Zoom out with mouse-wheel doesn't work in OpenLayers 2.12 with JavaFX WebView though it works fine with Chrome. Zoom out with mouse-wheel works fine with OpenLayers 2.13 and JavaFX WebView. 3. Text on the text layer gets displaced in the Java WebView. I initially thought that it's trying to keep its place with respect to the map div but that's not the case. If I zoom out or pan, it just goes out of the viewport. Any pointers regarding these issues will be highly appreciated. 1 and 3 are critical to our application.
