It would be helpful if you could get a shot of the Steam Link debug graph, by going into your SteamVR settings, enabling advanced settings, going under Steam Link, toggling the debug graph on, and then taking a screenshot when you encounter the problem.

I am worried you may be running into encode contention issues, but, it would be good to see either way to help diagnose.

I've been seeing this as well. The debug graph is under Steam VR settings?

I managed to enable the performance overlay - however, it only stays on-screen briefly until the screen "blinks" black for an instant, with the overlay being gone on it's return. The overlay button (hold 'back') is also not functional.

I’m having the same issue and have been unable to find a fix.

I'm having a similar issue to this. Randomly blinking black screen while streaming with the audio cutting out during the blink.

The other thing I have as well is when moving the mouse around the cursor is responsive but anything it moves over to highlight on screen is sluggish to respond to, same with mouse clicks and scrolling with the scroll wheel.

This is the exact same problem I'm having. It also seems like moving the mouse makes the black screen blinks happen more than if I don't move the mouse.

same, even on the FAST streaming settings

I am having the same issue since a few days, and moving the cursor is indeed increasing the issue during video streaming (extremely visibile on twitch website).
And the debug graph also disapear after the first black "blink".

Yah I can't get the debug graph to stay up either. Disappears when blink happens.

I found fiddling about with the streaming settings helped this - I enabled HEVC encoding and disabled all of the hardware-based encoding/decoding settings except for the one for my discrete graphics card (NVIDIA in my case). That seemed to stop the blinking, allowed the overlay menu to work, and kept the debug graph onscreen.

(I still get heavy dropping when the "boot screen" is being displayed when first connecting the Steam Link, but that's probably a seperate issue)

Tried these settings cause I'm also running an NVIDIA card but sadly it did not work to me. Mouse delay is still there and the blinking black screen is still happening.

Can you post a link to the Steam logs\streaming_log.txt on your PC? This sounds like the bandwidth for the stream is too high.
