I have the TitleMap with two cell options (wall and floor).
At start I am setting a fixed type for every cells in accordance on special Array. And in game my TileMap starts to flicker, like on this GIF.
(In this GIF flicker was weak, but in real it can be more strong)
I think that it may be due to redrawing map with every frame or too large cell's image.
I try to get rid of it, but I couldn't.
If anyone has any ideas how to remove flicker, I would be glad to hear them.
