How to reproduce:
1. Open that attached project
2. Open Test scene
3. Make sure that the Game View is using TextGlitch (669x509) as a size for the view
4. Look closely at the top and bottom text, specifically the "G"'s vertical line and the "e"'s horizontal line and you will see they are rendered differently
5. Play the scene
6. Notice how text glitches due to this reason

By Design: Issue is the canvas isn't set to pixel perfect. Thus the text rendering isn't aligning perfectly on a pixel which causes the visual difference.
