Bug ID: 489115
Summary: Screen sharing didn't work from Chrome / Slack since
6.1
Classification: Plasma
Product: xdg-desktop-portal-kde
Version: 6.1.0
Platform: Neon
OS: Linux
Status: REPORTED
Severity: grave
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: tchiot.l...@gmail.com
CC: aleix...@kde.org, jgrul...@redhat.com, n...@kde.org
Target Milestone: ---
SUMMARY
Since Plasma 6.1, no more screen sharing is working.
STEPS TO REPRODUCE
1. Open Google Meet
2. Click Share screen
3. Choose Windows or Entire Screen (Tab Sharing is working)
4. See the KDE Portal popup opening
5. Choose any one
6. You will see the KDE Portal popup closing (as usual), but the screen
selection from Chrome as going back to tab sharing
In the past, you will have to double choose the windows, and It's works. Now,
it's will be close in infinite and no more screen sharing is possible. Added
below some logs below with a kernel error on pipewire. FYI, Spectable is
working well
