Bug ID: 475496
Summary: Attempting to screenshare via Discord causes the
screenshare permission request menu to continuously
open
Classification: Applications
Product: XWaylandVideoBridge
Version: unspecified
Platform: Archlinux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

Target Milestone: ---
SUMMARY
I am attempting to use XWaylandVideoBridge to allow Discord's screensharing to
work while running under Wayland. With XWaylandVideoBridge active and
attempting to start a screen share session from Discord, the "Screen Sharing -
Portal" permission window comes up and asks me which screen/window to share.
Upon selecting one and confirming, the window re-opens a couple of seconds
later, and continues to do so unless I either move the window out of the way
and confirm / use the start option within Discord, or close the screen sharing
menu in Discord all together.
When moving the portal window out of the way and selecting the output that
XWaylandVideoBridge creates (and I can see the selected window/screen within
it), Discord doesn't actually appear to receive anything (the preview window
gets stuck at Discord's "loading" indicator).
STEPS TO REPRODUCE
1. Install XWaylandVideoBridge and launch it
2. Connect to a voice channel within Discord or join a call
3. Attempt to start a screen share session
OBSERVED RESULT
The Screen Share Portal window continuously re-opens, and the
screen/application doesn't seem to make it to Discord.
EXPECTED RESULT
A screen sharing session should properly activate
