@@ -413,3 +413,6 @@ Allow av1 in the flatpak. Do that by patching ffmpeg to support multiple nvenc c
 Increase qp on av1 non-nvidia, decrease qp on h264 nvidia. For vulkan.
 
 Check if the vulkan codec query works on nvidia x11.
+
+Fix webcam capture on nvidia x11. It doesn't work when capturing a webcam at the same time as capturing the monitor (nvfbc) because nvfbc requires glx context active (in older nvfbc version, works with egl in newer version)
+    while v4l2 requires egl. All other capture methods require egl so they cant be used together with nvfbc.
