I get the same thing but only when viewing from localhost. Once I
uploaded to the server the tile borders went away.

I am trying to make some custom mods to OpenLayers 2.11 -- nothing fancy, nothing in the JavaScript, only some of the buttons and images. So, I made a copy of my OL installation, and called it OpenLayers-copy, and replaced my OL script line in my web page like so

The click reported by the mouse position display is off from the click reported by the map listener even with the original OL library, albeit, by a smaller amount. For example, I clicked on [-78.35, 43.45] as shown in the mouse position display. The click event reported [-77.97, 49.61]. A very small lng shift but a fairly large lat shift.
