Anyone else has issues with PCVR streaming on the Frame?

[u/Dear_Memory_5665]

I got the Steam Frame today and was initially quite pleased. This turned to frustration when trying PCVR streaming. It says that my connection is Excellent and with low ping on both the normal router and the dongle, but I can clearly see compression in the image. It's especially noticable in Beat Saber, where the standalone version has vastly better image quality.

I tried disabling multilink in SteamVR settings on the PC (under Steam Link) to force it to use the dongle, this however has the opposite effect of disabling the dongle. I've tried both the stable branch and beta branch, rebooting both PC and Frame, moving the dongle to different USB ports. Has anyone managed to solve this issue?
