OpenRails crashing on alt-enter fullscreen/windowed toggle

[plethaus21]

I am running the current official "Testing" branch from the main openrails.org website, but I have tested the last stable version as well. The problem I'm having is that OR is crashing to desktop sometimes when switching from fullscreen to windowed (or vice versa) using alt enter. I do this because I have a Gsync monitor which needs exclusive fullscreen on Windows 10 in order to work. I was hoping there might be some combination of options or some other fix. Thanks!

This was in the Event Viewer:

Is Alt-Tab equally unstable?
