The old strategy of switching a transparent window to solid and back doesn't work on 10.11; it appears that queued messages must be handled for the window to become visible, but that's not allowed during a GC. The strategy for 10.11 and up create an OpenGL canvas, which acts as a direct-to-screen drawing area that a GC callback can affect without Racket-level allocation. |
