B Selection Box broken

Hello.

Whenever i use the Box selection tool to select some faces that i want to remove, it also selects some other random faces/verticies for no reason.
This isn’t the first time either. I’ve had this problem with other projects.

What is causing this annoying bug? is the tool broken?

Same bug over here. It appears only when selecting in solid mode and with the limit selection to visible off. In my case I was modelling a bottle, and previously applied a solidify modifier. I’ve tried blender 2.7 and some versions from graphicall, also tried to select edges, vertices and faces and the error persist.

This image shows what i mean.

Alright! Got it fixed.

I set the antialiasing to max (x16) and it fixed the problem!
I think i know why i sometimes get this problem

When im in object mode, sometimes I accidentally press P, which starts the game engine, and it ends up by setting the AA to the lowest.
Now when i set it to max its working like a charm

File>User Prefrences>System

Ill leave this open to see if it fixes it for @juanmartinez93

Yay!! that worked for me too! Thanks a lot!
