I have encountered this issue as well with the exception that it only occurs on layers that have no transparency (orthos for example) and it randomly shows up around only some of the edges of the images. The easiest "fix" I found for this was to set a gutter of 1 on the layers on which I notice this effect.<br clear="all">

I've been getting an intermittent problem with OpenLayers when running on a Mac with Firefox. The problem is that there is a while 1px outline around each tile in a TMS layer. At a recent conference in the UK, colleagues an I were joking that this was "tile grout". I can even see the problem on <a href="http://openstreetmap.org" target="_blank">openstreetmap.org</a><br>
<br>
Has anyone else seen this problem? I haven't tried it on other Mac's yet to see if it's a problem local to my machine. The other odd thing is that it seems to be intermittent.<br>
