Factorio Forums

Running the latest stable build the game crashes when trying to change the window size on a second display. Only the second display, not the laptop's main screen. I have attached the current log file for the game, there is no save (crashes before saving), and I am running no mods. The game also seems to run much slower when I move it to the second display.

Hi, it crashes in OpenGL function glDrawArrays.
First thing you can try is to open Factorio properties in Steam and set launch options to Second thing that might help is to set preferred screen to Screen 2 in graphics options in the game (then restart the game).

My other suggestion is to update your MacOS X.
