v0.9.4

What's new

GNOME

• Update button for the GNOME Shell extension. If the installed extension is older than the one bundled with WE Manager, the notice now offers Update extension. The old
  notice had no button and said a newer version was installed, which was the wrong way round. After updating, log out and back in once so GNOME Shell loads it.

Diagnostics

• New Diagnostics page in Settings. It shows what the running engines printed since they started, so you can see why a wallpaper misbehaves without starting the app from a
  terminal.
• Optional per frame timing output of the engine while you investigate (it costs a little speed, so it is off by default).

Engine options

• New --web-frames option for web wallpapers: auto, shm or dmabuf. auto is what you want unless you are chasing a problem.

Fixes

• COSMIC in virtual machines: the app crashed at startup on a virtio GPU because cosmic-comp refused Chromium's GPU buffers. WE Manager now starts with software compositing
  there.
• Installing missing runtime libraries now tells you whether it worked.

Packaging

• Flatpak/AppStream metadata: screenshots, keywords, branding colors, content rating and a longer description.
• README feature list updated.

Tested on

Each release is tried in KVM virtual machines with a real desktop session. This round: Fedora 44 (KDE, GNOME), Ubuntu 24.04, Debian 13 (GNOME, XFCE), openSUSE Tumbleweed (KDE,
XFCE) and Leap 16, Arch (Hyprland, XFCE), Manjaro (KDE, XFCE), CachyOS (KDE, Hyprland), Garuda, EndeavourOS (KDE, XFCE), Linux Mint 22.2, MX Linux, Zorin OS, Pop!_OS COSMIC,
Bazzite, SteamOS and elementary OS. The Steam Deck VM is still work in progress.

Notes

• Needs linux-wallpaperengine-kde with the same release for --web-frames.
• On GNOME, update the extension from the notice and log out and back in once.
