Summary

When komorebi attempts to resize (specifically expand) a Windows file explorer window, white artifacts appear. However, the artifacts don't appear if the window is resized manually by dragging the window borders.

In addition, this seems to happen with AltSnap's resizing functionality as well.

Output of komorebic check

No KOMOREBI_CONFIG_HOME detected, defaulting to C:\Users\DaNub

Looking for configuration files in C:\Users\DaNub

Found komorebi.json; this file can be passed to the start command with the --config flag

Your configuration file contains some options that have been renamed or deprecated:

"applications.yaml" is now "applications.json"
Found C:\Users\DaNub.config\whkdrc; key bindings will be loaded from here when whkd is started, and you can start it automatically using the --whkd flag
