On screen text appears blurry

Hello everyone!

I am currently experiencing an annoying glitch/bug. I am trying to make a graph for my parkour game, but the Y-axis labels appear blurry instead of clear like the X-axis labels.

This wasn’t the case the entire time. It only turned blurry after a couple of hours. After looking for a while on the DevForum, I couldn’t find any solutions to my problem.

Does someone know why this is happening and/or how I can fix it?
