Probably the dark background boxes behind the chat text. I programmed my own simple universal mod I could use with most games to adjust various aspects to my liking without modifying the game at all. Things like the background grey box behind text. I got rid of it and instead added a dark outline around the text to make it stand out. I enable developer mode and I like my screenshots to be saved as JPGs which are smaller but also save noticeably faster. I also enable the ability to scroll back (as some game disable that) and make certain certain keys remain enabled etc... etc... etc...
I made it for my own use, but have since added in a readme.txt explaining the files, what they do, how to use it etc... for anyone interested. I'll attach it here.
