Flatpak Chromium PWAs show the Chromium icon on KDE Plasma 6.8 (Wayland)

Since Plasma 6.8, KWin replaces a Flatpak app's Wayland app_id with the Flatpak ID unless the app_id starts with that ID (kwin 389d236). Chromium PWAs send chrome-<app-id>-<profile>, so every PWA window ends up as org.chromium.Chromium and groups under the Chromium icon. Upstream: KDE 527431, Chromium 584540048.

Workaround (without switching Chromium back to `--ozone-platform=x11`)

PWA windows are titled with the app name, and browser windows end in - Chromium. A KWin rule for each PWA can be set up to assign the correct .desktop file via the windows title.

Find the PWA's launcher:

get-winevent -ListLog * | ForEach-Object { wevtutil.exe clear-log "$($_.LogName)" }

install rustdesk server (OSS) on EL9 (RHEL9, Alma9, Rocky9, OL9) via podman quadlet (podman systemd integration) and auto updates (via podman-auto-update.timer)

server

systemctl --user enable --now podman-auto-update.timer
systemctl --user cat podman-auto-update.timer

# also make sure these ports are open on your cloud provider's security group/firewall

remove some major annoyances:

TERM setting that is more compatible with most real world apps
!= should be displayed as two characters, not one
don't ask when closing a tab (= don't block shutdowns/reboots)

#   ~/.config/ghostty/config

# https://github.com/ghostty-org/ghostty/discussions/3161
command = TERM=xterm-256color /usr/bin/bash
