I've avoided that bug throughout more than 20 years of Linux usage just by disabling raise-on-click.

(Except of course the Gnome folks did they utmost to make that option unavailable back in the Gnome 2 days: Metacity's raise-on-click gconf setting was hobbled so that it could only be disabled in focus-follows-mouse mode. That bit of idiocy was patched out years ago, but the obnoxious text that accompanied it survived in Marco until earlier this year!)
