I am hunting down a subtle but obnoxious bug in the way the IKImageBrowserView draws in iMedia. I confirmed it's a general bug and reported it to Apple:
What's interesting is the bug doesn't occur if the NSSplitView hosting the IKImageBrowserView is set to use layer backing.
For MarsEdit I'm considering making this switch, to work around this bug (and posisbly improve scroll performance? I'm not too up to speed with this).
What do others think about the possibility of switching to layer backed view for this part of the UI?
