Canvas doesn't line up with grid

[MegaMissingno]

On 16: Lasers I noticed the lasers wouldn't show on the right edge of the grid but would kill me anyway. Just ended up brute forcing my way through that until it worked. But then on 17: Pointers I realized it was simply that the canvas is thinner than the grid, and this makes it frustratingly difficult to impossible to read the lines I placed that are supposed link from one teleporter to another. I could still get through it if I had the patience, and I could probably just try and offset all my coordinates until they line up again, but I'm sure later levels will be even more troublesome anyway.

Oh weird. I'll see if I can reproduce this in Linux Mint.

Hotfix: Multiplying canvas X coordinates by 1.08 in your level code makes everything line up ;)

Having the same Problem

I'm not sure why this is so platform-dependent. We'll have to find a solution that works for everyone.

Oh strange, well you don't need the canvas to get pointers.jsx....

A problem is that the drawingCanvas is set to width 600 and height 500, but the screen canvas can have a different width.
