Hi, everyone, In an application under development, I'm seeing display artifacts at the boundaries of some rows of a fairly generic NSTableView displaying 1600 rows by 7 columns. The artifacts seem to be no more than a pixel high, and each one is no more than 5-10 pixels wide, if that. They appear at the bottom edge of their row. It's almost like they are remnants of the tops of characters, but they do not line up with the characters in the row immediately beneath them.
A couple of data points: - The objects bound to the table column values are Objective-C wrapper around ported C++ code; I'm sure the NSStrings I'm passing are OK, but the underlying code is hideously inefficient (for now), so it may be having trouble keeping up with the demands of the view. Even on my quad-core Mac pro. :-( ["Lucy, you got a lot of optimization to do!"] - I have to scroll to find the artifacts, so they may be created during scrolling. - We also see this on an older Intel iMac, but not ever on my 5-month old MacBook Pro. - I don't see it in other applications on the affected machines; i.e., it doesn't seem like a display glitch. Has anyone encountered something like this before? For now, I'm going to look at the optimization first before messing with what has been a very straightforward implementation of the table.
