Remove Alt-Tab Delay on GNOME (Fix Switching Windows Too Slow)
For Ubuntu, CentOS, Fedora and other Linux distros using GNOME will probably face an issue that switching windows with
Alt-Tab is really slow. That's because it has a 150 milliseconds delay by default. To remove the delay, there is an extension called
remove-alt-tab-delay. It supports GNOME 40+ and legacy versions.
Install the extension from GNOME Extensions with browser addons (Chrome, Firefox) or install it manually:
git clone git://github.com/BjoernDaase/remove-alt-tab-delay mv -r remove-alt-tab-delay ~/.local/share/gnome-shell/extensions Bash
Remember to log out and log back in after manually installed.
