Mac OSX Graphics flash when changing rooms

I have this problem only on Mac, not Windows or Android or iOS. When I switch rooms, the screen flashes to the wrong graphics for the time it takes to load the room. What I mean by wrong: on all the other devices, when I change rooms the screen just freezes until the new room is loaded and drawn. It changes from the old frame to the new one instantly once the room is loaded.

On Mac, when it goes to change the room, one of two things happens. It seems like it flashes back to the frame immediately preceding the current one -- like if my player steps into a door, it will show the frame just before he stepped into the door, for the duration of loading the room. If the player is leaving a house to go back into the outer world, I'll see a flash of a blank background -- indicative of how I am clearing all my tiles away to rebuild the world map. This is not something that should be seen.

It seems like some sort of double-buffering error, or maybe some difference in the way drawing happens on the Mac? Does that sound familiar to anyone? It's happening in GMS2 and I believe it happened in 1.4 too, I just never did anything about it then because nobody plays my game on Mac lol. But I would like to fix it if possible.

Thanks!

please file a bug with an example project so we can take a look - the smaller and simpler the project the better.

Help -> Report a bug is the best way to file a bug, File -> Export Project best way to package the project (this should make a YYZ).
