![]() On Cocoa, a view's `drawRect:' method can be called from a heartbeat thread that animates controls. Such a call happens rarely for a `canvas%' or other class where `drawRect:' is overridden, but since it can happen, ensure that the callback runs on the Racket thread. original commit: 57516164de983a9245bfee88cbf87b9ea5c13a25 |
