Map display blurry since 3.38

Stephan shared this problem 4 years ago
Solved

Since v3.38 my rasterimage maps are very blurry on my OnePlus 6. I think at the same zoom setting it is using a lower map-level then before.

I would like to have a higher map-level at a lower zoom level (more detail, when zoomed out).

I tested different offline and and online maps, as can be seen in the attatched screenshots. Vector maps are very sharp. The setting "increase map resolution" is off.

Guys, I have to ask:

  • are you aware of how these maps looked before? The fact that text labels were so tiny, that map was sharp but almost unreadable?
  • are you aware that raster maps do not scale so same raster image is used on old tiny devices as well as on new devices?
  • are you aware that raster maps are mostly optimized for display on the desktop, where you usually have huge 24'' monitor with only 1600px width resolution? Which is something completely different compared to new OnePlus 6 device with 2280x1080 on a tiny display.

And if you are aware of these facts, that only solution is increase scaling of raster maps on devices, so texts will be larger exchange for small blur effect in some cases. Sorry, there is no other solution.

In next Locus Map version (3.38.1, the start of next week), because there is more complains about the new rescaling then was before (even that raster maps were useless because they were unreadable), I've reduced rescaling factor a little bit ... you will see.

Re how the maps looked before and now. I have an old device with virtually the same screen resolution running the old version and my current device running the latest side by side. On the same point on a map at the same zoom level the latest version is definitely more pixilated and blurry

3.38.1 is better for me. Although you've described it will improve scaling, there's also a different change.


3.38.0 the zoom level changed when switching between raster and vector (e.g. zoom level 15 vector moves to 14 in raster)- in v3.38.1 the zoom level stays the same.

Better, fine.

Different change is just a side effect of reduced scaling on your device. App no longer uses something like zoom-level. When switching the map, the main point is to keep the same visible area and because raster and vector maps use a different system, there is a possibility that visible zoom level in top toolbar changes, but it is ok.

Same problem on Huawei P10 Pro since 3.38. v3.39 did NOT solve the issue.

[edit] I solved the problem by turning off the setting "optimizing the map resolution" in Advanced settings/Maps". > maybe it's "too much optimised" on zoomed maps (~1km) ...

Good day Colin, it sometimes depends on the maps and also users "taste". Anyway disabled "optimizing" revert scale to system before 3.38 version. That may be useful to someone ...

It actually is... So happy to have my 1:25000 IGN maps back to high rez... They look just gorgeous! ;)
