[BUG] steam VR link , macro blocking and trails with quest 3s

[tails101]

im trying steam vr linux and i get a very blurry image with tons of artefact.

it works on windows as it should.

tried to increase the bandwidth but nothing seems to work.

im using cachy os with kde desktop wayland (no gamescope) and my computer is a 5820k with a rx5700xt and 32gb ram.

the computer use ethernet and a dedicated 5ghz wifi router.

the fps are good on linux, i receive 90fps and flat game streaming works perfectly as well.

seems to be a codec issue in steam vr itself.

the headset is a quest 3s with steam link app.

any idea on what could be the problem?

Edit:
checked for and it blur even more the screen but it does not help sadly.

so yes it is disabled.

i tried as well to put the bandwith to manual and set it to max, did not help either . But it was helping before, I'm using Ethernet and wifi in same time.

It'd be helpful to get the SteamVR logs. In particular vrserver.txt, vrcompositor.txt, and driver_vrlink.txt may have useful information.

ouch sorry i used windows to play yesterday
because downgraded the version of steam vr expecting this would change a thing but nope
so i need to try the latest beta and try again.
im on wayland btw

[Packetdancer]

No worries, just if you can get logs under the latest beta it'll help figure out what might be happening for you.

And while it's useful to know you're on Wayland, it's also good to know which Linux distro, and what GPU you have.

[tails101]

Sure, as I said, distro: Cachy os
De: kde Wayland
GPU:5700xt

vrserver.txt

vrcompositor.txt

here you go.
after updating and everything still same issue

I'm seeing something similar, though I have a bit of DRI_PRIME in the mix, so it's not 100% certain to be the same bug.
Changing the bitrate slider to maximum does nothing to fix it.

I took these screenshots from the Quest 3's OS, then used the Android app to download them to my phone.

[tails101]

Definitely looks very similar, and yes before setting manual bitrate was fixing it a few month ago but it does not anymore.

I am seeing the same behavior with a Quest 2 and Bazzite-deck RX 5700 XT host machine. Bitrate is reporting as 1 Mbp/s in the debug tools. Playing with target bandwidth does nothing to resolve.

For what it's worth, I've also tried the same Quest 2 on a Fedora 44 KDE system running an AMD 760M iGPU and encoding looks fine there.
