Description Thomas Bertels 2025-07-05 08:10:27 UTC

SUMMARY
After making a video capture, if we click on the video recording link to open it with the default video player, if that player runs in Wayland mode, it opens without window management (no window controls, menus taking all the screen except the taskbar, impossible to minimize the video player).

STEPS TO REPRODUCE
1. Set Haruna (or any Wayland-enabled video player) as default video player
2. Make sure to use a Wayland session.
3. Take a screen video capture with Spectacle
4. Click the link in Spectacle to open the screen recording

OBSERVED RESULT
The Wayland video player opens without a window titlebar. 
It's impossible to minimize the video player.

EXPECTED RESULT
The Wayland video player opens normally.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
KDE Plasma Version: 6.3.5
KDE Frameworks Version: 6.15.0
Qt Version: 6.9.1

ADDITIONAL INFORMATION
This isn't Haruna specific and most likely isn't Spectacle specific.

Comment 1 Thomas Bertels 2025-07-05 08:38:42 UTC

When taking a screenshot and trying to open the file from Spectacle with ShowFoto, I get the same result.

With XnView, it doesn't open.
Log file entries:

I can reliably reproduce this with Dragon Player.

Don't use LayerShellQt::useLayerShell()

This sets the QT_WAYLAND_SHELL_INTEGRATION environment variable to layer-shell.

This propagates to all apps launched from Spectacle, for example when opening a
recorded video. If the app uses Qt it will be severely broken.
