Issue description:

Steps to reproduce:

1. select brush tool, yellow color, size 50, zoom out
2. draw a very small line from top-right to bottom-left
3. select erasor and try to erase what you created on step # 2. Doesn't work. It's uneraseable.

It also works with white color.

I'm able to erase it if I use an eraser of smaller size, but eraser with size 50 doesn't work for erasing strokes made by brush size 50 under the above conditions
