2D TilemapRenderer - low performance on Android

Hello, I'm working under beta release of my upcoming Android game... the game runs really well in editor, it's highly optimized, I've have long unity experience, although I can't figure out what's the cause behind the tilemaprenderer issue... I've removed everything from tilemap hierarchy, I've marked it as static.

I've done a simple sprite lit material, I'm using 2drender pipeline, with the most basic features, no v-sync enabled, disabled multithread-rendering to profile it.

I can't figure out what's causing such a behaviour? Why the geometry of the tiles is changed? Or it's a bug?

Ok, update it's not an issue of tilemaprenderer. Here is the profiler with disabled tilemap. So it shows tilemap is not an issue.

 

You have 3 rendertextures from the stats window. From what I remember, depending on what you are doing with those they can be uber expensive. Are you stacking cameras or anything like that? Any rendering code in Update() ?

How much overdraw is being done?
