Bug ID: 417856 Summary: Panel background unhidden before Firefox CSD window visually touches Product: lattedock Version: 0.9.8.1 Platform: Archlinux Packages OS: Linux Status: REPORTED Severity: normal Priority: NOR Component: application Assignee: mvourla...@gmail.com Reporter: prettyvani...@posteo.at Target Milestone: --- Created attachment 126152 --> https://bugs.kde.org/attachment.cgi?id=126152&action=edit Firefox with CSDs close to the panel SUMMARY With "Hide background when not needed" enabled on my latte panels the backgrounds stay hidden as expected when I have a Firefox window with normal KWin decorations until it actually touches or Firefox is maximized. When using Firefox with CSDs Latte behaves as if there was an invisible larger border around Firefox' window and becomes opaque quite a bit before it visibly touches. Maybe this has to do with the changes in Plasma 5.18 re better support for GTK client-side decorations with shadows and resize areas? STEPS TO REPRODUCE 1. Set a panel to "Hide background when not needed" that is otherwise opaque. 2. Configure Firefox to not use a "Title Bar" in its "Customize" view, thereby making it a client-side decorated window. 3. Observe the latte panel becoming opaque before Firefox visibly touches or is maximized.
