High-res displays cause mapsforge online maps to be drawn unreadable

Describe your problem!

I didn't play WhereYouGo in the last time, but just installed the beta-version 2022.01.22 to test it.

On my Samsung S20 the cartridge name and other text is hard to read. Changing font-size in the settings (WhereYouGo and System) didn't had any effect.

How to reproduce?

Additional Information

I found #76 but don't know if it is related, but appearently did not fix it on my device

I would also assume it sabout the tile-zoom / tile size as mentioned in #76 with its reference to the c:geo issue.

We had such problem in c:geo years ago and it was fixed this way (maybe needs a newer mapsforge version).

If someone wants to work on this:
The solution is described in cgeo/cgeo#7750 and the linked commits / PRs.

An extract of one issue comment there by @rsudev and base for the later fix by @jonas-koeritz

After researching for a while, I think I now know the background for this issue.
The zoom level relates to the tile the map is drawn with.

• Google map always uses tile size 256
• Mapsforge online always uses tile size 256
• Mapsforge offline uses a tile size depending on the the resolution (I tested mdpi through to xxhdpi):
  • Minimum (up to hdpi) is 256
  • xhdpi 512
  • xxhdpi 768

@murggel
Yes, #76 is the same IMHO. I copied the relevant information to here, renamed your issue and closed #76.

I was about to say that 2022.01.14 version still has this. Adding myself to this thread.
