Description Thijs Vermeir 2014-12-10 10:10:11 UTC 
This simple pipeline does not always produce a video playing on the screen:
gst-launch-1.0 videotestsrc ! glimagesink

With git version it works halve of the time. This problem is present in the last released version (1.4.4). 
This race condition is not present when GST_DEBUG is enabled :-(

It looks like the problem is in: cocoa/gstglcontext_cocoa.m:223.

dispatch_sync (dispatch_get_main_queue (), ... is never called (in the cases that it failes) so no window is created. I see in Apple's documentation [1] that dispatch_main() should be called from the applications main function to process blocks.

I'm going to work on that soonish... see bug #741054
