Created attachment 162776 [details] Video demonstration of the issue compared to the expected performance SUMMARY *** Streaming via XWayland video bridge has both very low refresh rate (less than once per second) and severe latency (~5 seconds delay until it reaches the stream) *** STEPS TO REPRODUCE 1. Launch XWayland video bridge 2. Attempt to stream (Discord Canary from Flathub-Beta in my case, same symptoms with Discord from Flathub) 3. Select a desktop in the portal, and the video bridge in the application OBSERVED RESULT Extremely degraded stream performance/quality, as described above EXPECTED RESULT Comparable stream performance/quality to directly streaming an X11 client SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora Kinoite 39 (XWayland video bridge now included by default) KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.110.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION Kernel: 6.5.6-300.fc39 GPU: 6900XT
Another user was able to reproduce the issue on Gnome Wayland when using desktop capture, but not during window capture. The issue occurs uniformly for desktop and window capture on my end.
I can confirm that I'm facing the same issue with the following setup: SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora Linux 39 (KDE Edition) KDE Plasma Version: 5.27.10 KDE Frameworks Version: 5.111.0 Qt Version: 5.15.11 ADDITIONAL INFORMATION Kernel: 6.6.9-200.fc39.x86_64 GPU: RX 6660
I can also confirm that issue, seem depending the resolution in use, If we use 2560x1440, it will be laggy If we use 1920x1080 instead, it will be fine

Experiencing the same problem in Plasma 6.0 (also in Plasma 5 before that), with xwaylandvideobridge version 0.4.0. For me it's laggy even on 1080p, but only most of the time. I do have two monitors connected though, so maybe it's making a difference, haven't tested that yet though. One weird thing that I noticed is that I get about one second of normal framerate when I switch between virtual desktops.
