I have a problem with anti-aliasing (I guess) in css. I've seen how to disable it on fonts and images but I'm having troubles with some borders... Here's the thing, I have a canvas wrapped by two divs, in a grid display. It renders nicely sometimes but with certain levels of zooms, a gray line appears next to borders. I figured out it was because of anti-aliasing but I can't find a way to disable it.
With anti-alliasing
What I would like to be always there
