README.md

Chromium-based project flags to work seamlessly work with Wayland.

Installation

1. Copy code-flags.conf to the root of the "$HOME"/.config folder.
2. Replace all *-flags.conf files, except code-flags.conf with the new flags:

find ~/.config \
  -mindepth 1 -maxdepth 1 \
  -type f -and \
  \( \
    -name '*-flags.conf' -and \
    ! -name 'code-flags.conf' \
  \) \
  -exec \
    cp -v ~/.config/code-flags.conf {} \;

code-flags.conf
