Describe the bug/issue

Hi.
I installed PhoneVR v2.0.0-beta on my phone and ALVR server v20.9.1 on my PC.
I'm having issues with jittery video on SteamVR and games (Falcon BMS, is the only game I tried so far).

A few extra information.
I'm using a POCO F3 with HyperOS 1.0.2.0.TKHEUXM (latest official OS version for the phone).
I'm on a 5Ghz wifi network without any other traffic going on.
I tried every setting I could find in ALVR Dashboard, from refresh rates (60Hz/120Hz) to encoder preset (Speed/Quality) to bitrate (5Mbps/30Mbps), and basically all other settings just to see if it changed anything, but nothing worked.
E reverted everything back to default and recorded two videos showing this.
The first video is in SteamVR, this one is hard to see because the recording is too dark, but it's definitely there.

The second video is in Falcon BMS and it's a lot easier to see it happening.

Can you suggest something to try so that I can fix this?

How about you try the v20.8.0 version ALVR Server ?

Sorry, I should've read the instructions a bit more carefully, you're very specific about the suported ALVR version.
Unfortunately it does the same thing.

I have a similar issue except the video stream doesnt show up on my phone. The tracking works tho
Update: i changed some settings including setting headset type to vive (dont know which setting fixed the video not showing up) but i get the same issue, very bad stuttering..

I ran into the same problem, again with HyperOS. The whole picture shakes so much that it's almost unusable.
