# Fixes texture corruption in VS Code terminal after resuming from suspend.
#
# Place script in /lib/systemd/system-sleep/ so it can run after resuming
# and edit the CONFIG variable with the location of your settings.json
#
# Based of stephan-t's https://gist.github.com/stephan-t/561d0e473dddb270be3da6a8ca994306
# but without the jq requirement or 5s login delay and works with dotfiles (symlinks)
#
