i have no idea what the white triangles in the dock are from. if i scroll a small amount in the dock they show up as white triangles next to the black triangles of open apps.

scroll far enough away from the application and they dissapear.

any idea's to what they are, are they not supposed to be there, or am i just not grasping an obvious idea of why they should be there?

thanks

ok maybe it is because i just woke up. but i never thought about this before. but in tinker tool i had the enable dock shadow on, i turned that off, white triangles go away, turn it back on and they are back.

anyone else got this problem with the tinkertool dock shadow?

They're just artifacts from the black triangles--the Dock doesn't always redraw itself properly. If you do something that forces the Dock to completely redraw itself--like resizing, or doing something that requries re-launching--they'll go away.

I think that you've answered this yourself: it's the drop shadow. Basically, drop shadows don't get updated in the Dock in real time, so the black arrows would be spots where it doesn't draw a shadow, but the arrows themselves throw a shadow. therefore, the Dock isn't updating them properly for whatever reason (maybe because TinkerTool is adding them, and the Dock 'assumes' that it doesn't have a shadow?) , and you're seeing the drop-shadow artifact.

We had to struggle with this a little bit when we wrote CodeTek VirtualDesktop; our Pager window can have a transparent background, so the drop shadow can be a weird custom shape, so we have to manually update & invalidate the old shadow when the Pager changes.

Yes, that's it.
I didn't notice these artifacts at all until I saw the post above... then I could see they were there. I turned off Dock Shadow in TinkerTool and relaunched the dock from the terminal. Artifact gone. Interesting.
