Steam Link not working anymore with VAM

[checkking]

Since today, when I open VAM with Steam Link (Quest Pro), there are huge framedrops and screen freeze. This happens every 1 or 2s and the image move suddently then comes back, making Steam Link totally unusable.

• I tried other games with Steam Link, but they work smoothly.
• I tried Oculus link and VD and both work fine.
• I tried on another VAM install, same result.
• Also tried to reboot, update nVidia drivers, etc.

That seems to be a very specific case of VAM and Steam Link since the last Steam Link update, but I have seen nobody talk about it yet.

Anybody in the same situation?
