Sprite white outlines

How do I deal with the white outline that appears around any sprite that I insert? I can't even overlap two sprites visually (for example to create a platform's edge) as there are always that white lines that don't allow me to do that. Tested with different settings (webgl on/off, pixel roundings, etc.) and on different graphics cards. I found the same problem on forum in 2014 but there is seemingly no resolution to this problem yet.

Are you resizing in the sprite editor? If so, this will often add a slight gradient to the edge of the sprite.

If you're simply need a large single colour sprite, try using a tiled background instead; you can make it a small 8x8 block and then drag it to whatever size you want.

No, I didn't resize anything. That was just an example. I have the same problems with tiled sprites. What I need is to create two tiled sprites - one would be the main body and one would be the edge (of the terrain, for example). And due to this edge gradient I can't overlap them to create a single visual terrain.
