The problem seems to happen only with 64-bit builds on 10.11. I don't know why, but 10.11 changes the way that windows are drawn in a fairly deep way, and it's probably something related to that change. Fortunately, MiMo42 provides MMTabBarView as a replacement for PSMTabBarControl. It only works on 64-bit 10.9 and up, but that covers the case where PSMTabBarControl is a problem. Also, MMTabBarView includes a Yosemite style. So, I've switched `racket/gui` (and therefore DrRacket) to use MMTabBarView on 64-bit 10.10 and up. > (You saw that I opened a PR for this?
