Summary: Steam in home streaming/Steam link shows a black
screen on wayland session
Classification: Plasma
Product: xdg-desktop-portal-kde
Version: 5.93.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: mmboss...@gmail.com
CC: aleix...@kde.org, jgrul...@redhat.com, n...@kde.org
Target Milestone: ---
SUMMARY
When running steam under wayland session (host) steam link only shows a black
screen (at least on an android device client)
STEPS TO REPRODUCE
1. Start steam with either -pipewire or -pipewire-dmabuf
2. When requested by portal, choose a monitor to share
3. Run steamlink on android device and start streaming
OBSERVED RESULT
Black screen on client, audio and input works fine
EXPECTED RESULT
Steam is properly shown on client device

Notice I've opened this to KDE because I've tested on Gnome (opensuse
tumbleweed) and there it works fine
Also tested on Fedora and got the same problem with KDE 5.27.10
After streaming starts, terminal get flooded with
CDesktopCapturePipeWire: Couldn't import dmabuf: Function not implemented
CDesktopCapturePipeWire: Failed to mmap memory: Operation not permitted
CDesktopCapturePipeWire: Couldn't get image data
