--- Comment #4 from Ismael Asensio <isma...@gmail.com> --- I'll try and dissect this bug report in two parts - About the "Apply Now" policy: It is expected that the rule disappears when it is set to "Apply Now", because it is a one-time-only setting. The same thing happens for "Force Temporarily". I understand this can be unexpected so we may work on disabling them (not as obvious as it seems), but it would be a feature request. - On the rule not applying just for this case, that might be a case of being set to apply to all windows (which is generally disallowed), but getting deleted after the first shot. Can you check if this happens for other properties (ej. titlebar color, which is easy to test) also on "Apply Now"? This will help to better track the cause. Also note there are better ways to not draw window titles than using window rules ;) but a bit hidden: Go to System Settings > Window Decorations. Over the Breeze decoration, click the "edit" pen button, then go to "Window-Specific Overrides" and add a new exception. There you can also match some windows and set "Hide Titlebar" -- You are receiving this mail because: You are watching all bug changes.
