I have a leaflet app that makes a WMS call to geoserver (tested on both 2.8.3 and 2.9.1) to display a particular layer and I use the tiled=true and tilesorigin parameters to fix the multiple label issue. It works as expected usually, but when panning around in the application, a tile will periodically be missing (not displaying the layer data). If I zoom in or out, the data that was previously not being displayed will display, but I will then usually see the issue in a different location at the new zoom level. If I change the app to not pass in the tiled=true and tilesorigin parameters, I do not have the “blank tile” issue, but I am back to having multiple labels displayed. Any thoughts on why these parameters would cause this issue? Looking at the geoserver logs, I see the following when the issue occurs:
