When using non-default maps, i.e. Google or VFR Sectionals, zooming with the scrollwheel makes the map blurry. If I zoom using the arrows displayed on the map, then it works fine, but for some reason those zoom increments are not matching what the scrollwheel does. This is also a problem when using an offline map that I made myself.

In older versions, up until this year or so, all of these map themes used to work fine. Am I missing a setting somewhere?

It's the known problem discussed here: 

If I remember well it was discussed under 2.8.11 period (.12 was released later - in July). Personally I suppose it's rather a Google's side problem. I've noticed the Google  sometimes changes suddenly some things in their APIs (like some days ago - problem with the old keys) or other areas and then there is a problem if someone bases on their solutions.
If you use Open Source solutions like OSM, Mapbox or similar maps then there is no problem, as the all specs are open, and even when something is changed the developers can make quick corrections to their codes.
That's why I usually use standard (tested by Alex) LNM themes/maps - there is no problem with them 🙂

ps. Have you checked older LNM versions at this moment (not week ago or older time)?
Please report which version  is the last one that works correctly with Google/sectional themes at this moment.

There were no changes in zoom level handling on my side. Maybe the Google maps DGML configuration file which comes with the themes changed?

I already tried to to fix the zoom steps in the Google maps but did not succeed.
Frankly, I'm not too eager to fix this, as there are plenty of other and better map styles coming with LNM, in my opinion.

Addendum: Using Google maps this way violates the Google EULA. Not your problem and nobody will sue you but this is one reason why the maps are not bundled with LNM. Just trying to avoid issues.

The version I had on my old PC was 2.6.4.beta. Just downloaded it this morning and the maps work correctly.

 

I do not care much about the Google maps, I understand there are compatibility issues and it's not worth the time. I hardly ever use them anyways. Just curious why the scrollwheel doesn't align with the map controls like it does in the older versions. Maybe there is a new setting somewhere that messes with the map zoom?

The only settings for map zoom are in the DGML file. I tried various settings but could not find anything which fits. The related settings are in the zoom section:

      <zoom>
        <minimum>   900  </minimum>
        <maximum>  3500  </maximum>
        <discrete> true </discrete>
      </zoom>

Going through all the .dgml files and changing <discrete> false </discrete> to true for the problem maps has fixed it. Thanks for the hint.

Thanks a lot. Good to know.

"<discrete> false </discrete>" is meant only for offline maps which can zoom in and out smoothly. Online maps use pre-rendered image tiles for different fixed zoom levels and therefore use fixed zoom levels. I'll check all the map themes I have access to.

Edit: Oh dear. No idea how these wrong discrete values crept in there. I fixed all maps in https://www.littlenavmap.org/downloads/Map Themes/

Google and similar doesn't matter for me, but Sectional Charts are the base for VFR in US.
Thanks for this hint🙂

Glad to help! LNM has been indispensable, thanks for the hard work.
