My res is a weird one. game is at 2560x1440 but because i play it in windowed (and sized down a bit) it's a really obscure res. Somewhere in the 23xx x 12xx area. For my weird screen res i use Mecha at size 14 for it to display right with monochrome outline.
The reason my screen is at a funky size/res is because at certain res/window sizes some borders just won't show up on say the left, right, top or bottom (either one would be missing) So i had to fiddle around with the window size to get everything to show up.
My screen is a 27" so could be why there's so many quirks.
Also setting Multisample to 1x helps a lot.
