screencast: unable to use screencapture a second time on firefox #181

Closed columbarius closed 2 years ago

columbarius commented 2 years ago

Distribution: Archlinux

Steps to reproduce:

Goto https://mozilla.github.io/webrtc-landing/gum_test.html
Start screencast -> Select "Use os ..." -> ... -> Screencast is running
Stop screencast
Click again on Start screencast
No UI element to select the Screencast provider ("Use os ...")

Restarting firefox will reset this circle.

Tested with firefox 96 (arch and flatpak) and xdpw from master.

This issue does not occur with the gnome wayland session.

Using dbus-monitor "interface='org.freedesktop.portal.ScreenCast'" "interface='org.freedesktop.impl.portal.ScreenCast'" "interface='org.freedesktop.portal.Session'":

The logs were generated by trying to start two screencast sessions using the flatpak versions of firefox and chromiums. Note: chromium will always create to double amount of screencast sessions because of it's preview.

Update: Falling back to sway 1.6.x solves this issue

I think this is fixed by https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3436

Yeah, wlroots 0.15.1 was released which fixes this problem. Closing the issue.
