Description

Hi,

I've noticed that in the nautical view once you enable depth contours the rendering becomes very slow and sometimes just stops rendering tiles alltogether. This has been going on for a few updates now (I've seen the same behaviour on 4.7 and 4.8)
This seems strange as my device has no trouble rendering much more complex contour lines for standard elevation.

While looking at the logcat data, there was around 3000 errors like so:

Steps to reproduce

go the the Nautical view profile (boat profile), download and enable the Depths contours in the settings, span, zoom and roam around the map, notice the slowdowns and errors in displaying the tiles.

Actual result

Rendering in general is much slower than other profiles, and notice at the end that osmand stops rendering tiles alltogether (and required a restart to start functioning again). The screen was responsive, you could span around and interact with the UI but no map was loading

Expected result

Rendering is smooth and doesn't stop loading tiles.
