At zoom level close to 0, if I update the view with a new projection, OpenLayers doesn't request all the tiles, only some of them. I have to pan or zoom in and out to make it request all the tiles.

I can understand that this s useless if I only update the zoom level or the center, updating the projection should cause all tiles to be requested from the server.

Is this a bug or is any there a way (or workaround) through configuration or code to make OpenLayers request all tiles after changing the projection?

Note that I disabled the browser cache.

    Are you doing something similar to https://openlayers.org/en/latest/examples/projection-and-scale.html but with more projections? If so which projections. Also what is the native projection of the base layer? – Mike Jul 21 '22 at 21:16
  • No, I don't care about keeping the exact same resolution. I just want to change the projection at world extent level, and then see all the tiles requested. I've tried switching from EPSG:3857 to EPSG:4326 and back again. The native projection of my base layer is EPSG:4326, but the same happens with several external WMS servers. – Vincent Blandin Jul 22 '22 at 12:54
  • I think it is making too many requests to the WMS server - I found a similar problem in one of the OpenLayers examples and reported it https://github.com/openlayers/openlayers/issues/13866 – Mike Jul 22 '22 at 14:34
  • I don't think as I don't see a lot of requests coming out from my OpenLayers client when look at them with DevTools. The requests are in fact much less than normal. – Vincent Blandin Jul 22 '22 at 15:55
  • I have implemented a workaround by applying a refresh to base maps that have a global extent right after a projection change at low zoom levels. But to me the problem looks like a bug of OpenLayers. By the way I am using OpenLayers version 6.12.0. – Vincent Blandin Jul 26 '22 at 07:35
