Description

This happens after unplugging my external monitors and then calling hs.grid. Running with hs.grid.setGrid('6x3') and hs.grid.setMargins('0x0') if it impacts anything in any way

Research direction
Review the hs.grid source code in Hammerspoon's repo, particularly the screen change event handlers. Look for any caching of screen dimensions that might not be invalidated when monitors are disconnected. Check if there are any existing tests or related pull requests. The issue provides no code snippet, so reproducing the bug requires a multi monitor setup and unplugging external monitors.
