            Bug ID: 450931
           Summary: Screencasting full screen games does not work
                    (screencast is black or frozen on last frame)
           Product: xdg-desktop-portal-kde
           Version: 5.24.2
          Platform: Fedora RPMs
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: plasma-b...@kde.org

  Target Milestone: ---

SUMMARY
On Plasma 5.24.2 on Fedora Linux 35, I have discovered that screencasting full
screen games does not work.

When I try to screencast using OBS Studio (v27.2.0) to Twitch, the only time
the screencast updates is when the desktop is in view. When I'm in the game
itself, the screencast completely freezes and no frames are being streamed to
OBS Studio. I observed this issue with Sonic Lost World, Sonic Adventure DX,
Sonic CD, and Sonic Adventure 2: Battle from Steam.


STEPS TO REPRODUCE
1. Install OBS Studio from RPM Fusion
2. Install any one of the games in the description and configure for full
screen at native resolution.
3. Attempt to stream/record the game in OBS Studio while playing it.

OBSERVED RESULT
The video stream in OBS contains the last frame (or sometimes just nothing at
all) while the audio is continually streamed in.

EXPECTED RESULT
The video stream in OBS receives and records the gameplay as I am doing it.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora Linux 35
(available in About System)
KDE Plasma Version: 5.24.2
KDE Frameworks Version: 5.91.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
This previously worked with Plasma 5.23.5 on Fedora Linux 35, as I streamed
playing Sonic CD to Twitch a few weeks back doing so.
