Since I've started texturing with the beta, There's been this white outline on my finished projects in the game.

You forgot to remove the white background from the sprite. The default sprites may look like they have white backgrounds when you look at them with your image viewer but it's actually transparent. Make sure you manually erase the background instead of just painting it white. It should appear checkered or pink depending on the tool that you're using.

Also ensure the transparent space is actually saved as transparent and not turned white at the save conversion process (MS Paint does not have this functionality, creating sprites with the default Windows image-editing software is always going to save backgrounds as white. Find a different program to save sprites with [e.g. paint.NET] or use an online tool to remove the white background when you finish working on the sprite).

We transform magenta pixels (255, 0, 255) to transparent pixels automatically. So you could use MSPaint if you want.
