As a temporary measure, I downloaded a prebuilt MacVim.app from Macupdate. It works, but the window _blinks_.
Same with the kshisen app that I got built once I followed a suggestion how to get libkdegames built. They're not even using the same copy of the Qt/KDE libraries, since the downloaded MacVim.app must have bundled all its own. WTF? This is about as freaky as mpv having blank windows.
