Bug ID: 475505
Summary: Ending portal does not stop screen cast
Classification: Plasma
Product: xdg-desktop-portal-kde
Version: 5.27.8
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: j.eym...@gmx.net
CC: aleix...@kde.org, jgrul...@redhat.com, n...@kde.org
Target Milestone: ---
SUMMARY
***
When sharing the screen in a Plasma Wayland session using TeamViewer, the
screen cast continues to get transmitted even after the user has stopped the
portal session. This can have potential security implications as the user is
wrongly assuming that the session was stopped.
***
STEPS TO REPRODUCE
1. Install recent TeamViewer version on a system running KDE Plasma (tested
with Fedora 38 and KDE Plasma 5.27.8)
2. Connect to the system when running a Wayland session
3. In the status bar of KDE Plasma, click the screen icon indicating an active
remote desktop portal session and click "End"
OBSERVED RESULT
* Remote input gets stopped properly, but screen cast is still being updated on
the remote side
EXPECTED RESULT
* Screen cast should not get updated anymore
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Fedora 38, KDE neon testing
KDE Plasma Version: 5.27.8
ADDITIONAL INFORMATION
* TeamViewer should also close the connection due to the stopped signal. This
is a known issue at TeamViewer (however, this would then hide above problem)
* I found this merge request which might be related, but I think it was only
merged to master, i.e. not the 5.27 branch:
