Screen on sink display goes black when an application is being displayed in full screen
Hi, I am running gnome-network-displays under Linux Manjaro with Gnome 3 and X.org (compiled from AUR, via package manager).
I am able to get a stable connection to a MS Display Adapter v2. Everything seems to work smooth, even audio
The affected app(s) are games emulated via archyPie, a retropie clone. Everything works fine if i can successfully force emulationstation and retroarch into windowed mode, but once a game is being run the output disappears on the sink display.
It comes back even if you tab out and another window is becoming active. if you tab back to the full screen app the window of the other apps disappear, but the screen goes black again. Running with G_DEBUG_ALL showed nothing suspicious, except "cannot force key frame" (two or three times) And running the app "emulationstation" on its own in fullscreen mode -> same behavior. Windowed works fine. Same with retroarch itself.
Hmm I suspect somewhere the streaming code doesnt like it when no windows or no window decorations are shown. What exactly happens in fullscreen mode internally, or when switching to it ?
Edit: When running under wayland, only a first frame is being shown on the sink display, and keeps stuck until the connection is closed again
