Issue description

Tiles overlap on a repetitive pattern (right and left on the following screenshot):

Steps to reproduce

Using the tile in reproduction project (isometric, 100x226 where the "ground zone" is 100x200):

1. Create a Scene (Control in my example, you can change the Scale to x=0.5,y=0.5 to get more information on screen)
2. Create a TileMap
3. Add a new TileSet
4. Change the Tile Shape of this TileSet to Isometric
5. Change the Tile of this TileSet to x=200,y=100 (image 1)
6. On TileSet add a new Atlas
7. Set the Texture with tile in reproduction project (Answer No if Godot ask to auto generate tile)
8. Change Texture Region Size to x=200,y=126 (image 2)
9. On tile properties update the Texture Offset to x=0,y=-26 (image 3)
10. Draw tiles and reproduce the bug (image 4)

This is an expected behavior. TileMap is using different quadrants, which are different CanvasItems that are drawn in batches.
If you need to add a vertical depth to Isometric tiles like you are doing now, you need to enable Y-sorting on your layer.

Are you talking about this ?

I don't see any change but may be I checked the wrong option.

[groud]

Yes, but you also need to enable it on the TileMap node itself. In the Node2D/Ordering category.

OK thank you. It was not obvious at all. New tiles editor is really cool but much less intuitive than the old one.
