Ocean/Land rendering error in v2 OpenGL that is not present in v1

[dangxit]

Description

For some of the costal area the ocean layer is rendered above the land layer of the map, at a certain range of zoom in the V2 OpenGL engine. The zoom range is roughly between 500m:1cm to 50m:1cm. The issue is not present when using the V1 engine.

How to reproduce?

Issues only occur at the specific location of the map when viewing between roughly 500m:1cm and 50m:1cm . The one I found is located in Zhuhai, PRC at 22.28678° N, 113.57270° E the ocean area is rendered above the land area

@DmitryAlexei please check different zooms probably this is not relevant any more cause maps are updated.

I checked this place with different zoom levels and with old and new rendering engines. I cannot observe it there. But near that place can be found other related to rendering (or map source) issues:

1. 21.99641° N, 113.27231° E

3. With OpenGl Hong-Kong and Macao maps displayed as downloaded (in green color) while they are not. With rendering version 1 works fine. See difference in old (left) and new rendering:

Also see ponds near ocean at 22.06164° N, 113.01018° E :

This behavior also persists with the old rendering

@vshcherb has this issue been fixed? I am seeing similar issues with OpenGL rendering that I cannot reproduce with V1 rendering.

I am using 4.3.12 on a Fairphone 3.
