Background image issues

When you have multiple monitors that are not set up in the same orientation (I have 3 in landscape, landscape, portrait), when yabai opens new spaces, the background image most of the time is cut off with black boxes, which is slightly annoying.

This does not happen when Yabai is not running, so it leads me to believe that it is an issue.

No files, tests, or entry points are named. First reproduce the report with three monitors arranged landscape, landscape, portrait, comparing new spaces with yabai running and stopped; done means background images no longer show black boxes or are cut off.
