This requires an image for explanation.
The top line is using the: SpriteFont+ plugin
The bottom line uses the raw Construct SpriteFont.
Both use specific spacings for each character.
The scales on the above fonts are:
0.56
0.51
The lines are faint vertical lines roughly 1-2px in width that seem to randomly (depending on scale) scatter themselves within the SpriteFont. If I scale to 1, they go away, but I cannot afford to have everything as scale 1.
I suppose we could go back and make the original spritesheet image smaller (allowing us to avoid scales < 1), but the SpriteFonts definitely do not work happily for scales smaller than 1.
The original sprite font image (used for both) is here: http://s3.postimg.org/4p7i0qdap/Sprite_ ... _0_4_1.png
These rogue lines are my primary reason for being hesitant about using the SpriteFont despite the significant performance losses that we are going to eat using thousands of Text objects.
