I experience this bug in Plasma 5.27 on Wayland. Do you have it on Plasma 6 (testing) on Wayland?
When I click on link for example in some note app like Kate or LO Writer it opens in Firefox but this Firefox window doesn’t move to become displayed. I need to click on panel icon to bring it forward (to see it).
I am just curious if it was fixed. Forgive me but I am not that brave to switch to testing myself. I just want to find out what to expect with upgrade.
I need to add that this happens when both apps are on host (meaning manajaro packages). When both note app and browser are on Flatpak it doesn’t occur).
