Alright, hope you get it fixed. Please post back on here when you try all that to notify others for it to be helpful for others.
Also, one last thing I forgot to mention. When you change the font numbers for those settings in that list below, try changing every single number to something that is a different number and a bigger font, and restart the computer. If that fixed it, reset those numbers back to what they were, restart computer. If that brings back the bug, do them one by one to eliminate whatever one it could be.
This is assuming that this is the issue. Hopefully it is! Then no need to get used to that tired little arrow.
