Weird Background Issue

[zechmann]

Once in a while my backgrounds will have a bright line going down the bottom or sides and the background is off on some sides... i included a picture... the backgrounds are all perfect res (1440x900)... what is happening?

edit: you can barely see the line at the bottom but it's only about one pixel and usually a bright aqua... you can see the things one the left and right though (those aren't there in the original)

no one knows what this is??? It's really pissing me off and I can't think of a logical explanation

hmmm check to see if it's "tile" when you select your desktop in system preferences. For me sometimes when I switch a background to another and it's under tile, something similar happens.

I second that opinion, def looks like it's tiling.
