I tested a bit (Lix 0.10.29 - release build - win64 - Allegro 5.2.10):
Either:
Out of VRAM error:
193.41 src\basics\alleg5.d:26:
193.41 Out of video memory. Can't create bitmap of size 913x946 with flags 5120.
Or:
Graphics stutter for 0.5 seconds or 1 second. After that, Lix continues to run smoothly without further stutter. But if there was terrain modification in that 1 second of stutter, e.g., a builder was building, then the newly built bridge slap is not drawn, and will continue to be invisible throughout the future:

- Monitor no. 2 is set as primary monitor.
- Before play, go to Windows's monitor/display settings, and choose: Extend the display to all screens.
- Start Lix.
- Observe how Lix starts on monitor no. 2 in software fullscreen.
- Start a level and play.
- During play, go to Windows's monitor/display settings, and choose: Display to only monitor no. 2.
