Graphics get messed up at runtime. Strange vertical an horizontal lines appear. 2D graphics project settings.

Godot Version

<3.3.4>

Question

I have a 2D game that looks fine from editor but strange lines appear and mess up art at runtime. I’ve tried messing with project settings but haven’t managed to get it to look proper. All art is imported as Texture, 2D Preset. Any ideas how to fix this or what are desired project settings.

Any screenshot to show what’s happening? It always help when we have a visual to help fix visual problems.

3.3.4 is a very old version - is there a reason to be using it?

I have to use it because it is Htlml5 game and this version has better compatibility for different devices and OS.
