Whenever I press F3 I see a long line of words that are covering the coordinates. I've tried changing it but nothing will work.
You have a few options...
1 - Resize your Minecraft window. If you make it wider the text should align better:
2 - Get a resource pack with a decent font (something narrow or smaller). With the text being smaller it should no longer overlap that far.
3 - Not really an option, but if you run Minecraft on a graphics card with less text in its name it would resolve your issue as well.
