Implementing this doesn’t seem to make any difference. I checked that it is called. In any case, the release notes say that responsive scrolling is not active if you link against 10.7, which I do.

Since moving to 10.9, the textfields which are in rows which are out of view when the table loads are rendered all black when those rows are scrolled into view. This is new behaviour. Is this supposed to happen? In other words, did I miss some changes in the release notes which indicate I should do things differently now? Clicking in the offending textfields causes them to then draw properly. The reason I have subclassed NSTextField is because I draw them in different colours depending on the colour of the row background they are embedded in. My drawRect: is below, in case there is something fishy in there that might be causing this.
