--- Comment #1 from Ismael Asensio <isma...@gmail.com> --- It seems you set the rule to "Force temporarily" (blockcompositingrule=6) By design this setting forces the rule while the window is active and then deletes it, since it's a temporary setting If you'd like to have it permanently please set it to "Force" instead. There's a bug though, and it's that it keeps it on the kwinrulesrc file. -- You are receiving this mail because: You are watching all bug changes.
