The reason for flicker is because when you write new text, it doesn't wipe out the old text. So you end up with new text over top of old text. The only solutions I've seen are to either write a rectangle over the text first, then write the new text, or as stated here to write the old text in the background color, then write the new. But yes, I did try it out, and it does happen. Again, it's really just the text being blanked out then re-written. So what I'm came up with here was a way to only place the rectangle over the digit that changes, then re-write the value. Since the one digit is changing, it doesn't have the flicker look, and the rest of the value never changed, so even though it's being re-written, it's over the old text which is exactly the same.
