[Oxyd][Linux] Repeatable segfault on "xrandr ... --off"

[dwhughes]

I am on a Thinkpad T510 laptop (specs). I use xrandr to switch between the laptop screen (output LVDS-0) and my monitor (VGA-0) by using xrandr. (I do this in two separate operations because my window manager (i3) sometimes didn't like an atomic switch.)

Code: Select all

xrandr --output VGA-0 --auto
sleep 3
xrandr --output LVDS-0 --off

If Factorio is running, it repeatably crashes on the "xrandr ... --off" command. This happened whether I was switching from VGA-0 to LVDS-0 or the reverse.
