White horizontal stripe across screen while using link

Headset seems to work fine stand-alone.  I use the headset with IRacing, and often (not always) get a translucent horizontal stripe across the screen after about 15 minutes or so.  It doesn't feel like the headset is overheating.  This doesn't show up on the screen mirror on PC, or if I "mirror" with the debug tool.  Is this likely a failing display or is there somewhere else I should look?

    UPDATE: POSSIBLE WORKAROUND/FIX USING REGISTRY EDITOR

    As I theorized above, this issue does NOT occur for those who use Air Link. Air Link uses HEVC and uses 1 slice for its encoding, whereas wired Link uses H.264 and 5 slices for encoding. Whenever the white bar issue occurs, it is very likely the final 5th slice experiencing an error in the encoding. If you pay close attention when this occurs, you will likely notice it only occurs in the bottom slice of the screen.

    To use this workaround, open Command Prompt and use the following:

    • reg add "HKEY_CURRENT_USER\SOFTWARE\Oculus\RemoteHeadset" /v "numSlices" /t REG_DWORD /d "1" /f

    I will be experimenting with this for the next few weeks to make sure  I do not get the white bar issue!

    Original Post on REVISITED thread:

    I have noticed that this is related to the horizontal encoding slices that are visible only through the Link Cable. A very easy stopgap solution would be to offer a toggle in the OculusDebugTool that allows us to turn OFF these encoding slices. Additionally, the encoding slices do not appear with Air Link and thus the issue has almost never occurred wirelessly according to both personal experience and these threads.

    I too started having this issue. I get this when running Dirt Rally 2 via Steam using the link cable and I also have the issue using Demeo from the Oculus Store. Playing Demeo native on the headset has no issues and I can play everything else I own countless hours without having issues. 

     

    System Specs:

    MB - Asus Maximus X Hero Z370 Chipset

    CPU 8700k OCed @ 5.0

    GPU - RTX 3080 TI

    Ram - 32GB Gskill Trident Z 3200 

    PSU - Corsair RM850x

     

    I opened a ticket with Oculus yesterday about the issue and they had me do the typical troubleshooting steps but nothing has helped. 

     

    I did just upgrade my video card to the 3080TI but the 1080TI didn't run the Quest 2 well enough for me to use it much over my Vive until I got the 3080TI to know if the issues was happening then or not. Plus I just got Demeo and Dirt Rally 2 this week. 

     

    Has anyone else had this issue with Demeo?

    Hi,

    I'm following this topic since the begining, I've never read a message from someone saying to have this issue with Demeo.

        Same here ...
        Happening in dark zones, like Elite Dangerous space.
        The white band frequency and happening is totaly random. One day nothing, the other day full white band as soon as I enter Oculus Link menu. Monthes ago, quickly switching from game to Oculus menu did wipe it up for awhile, but nowadays it comes back under 5 minutes. It's horrifying.

         

        Just like others, it starts as a very hollow band, which loses more and more transparency over time. Like if the same horizontal band was layered several times. 
        The band is always the same exact size. Sometimes, 2 horizontal bands appear, same size, one perfectly docked under the other.

         

        Pc app 31, Oculus Quest 2 firmware 31.

        I'm on a i9 9900k, 32go ram, 3080ti.

        Happened on 2080ti aswell.

        Official Link cable, 2.4 gbps speed tested.

         

        I checked temperatures, they are in the nominal range.

        Also Air Link gives huge artifacts aswell.

        Definitely an encoder issue (or Quest 2 decoder ?). This is not good.

          I have tried everything Oculus has suggested...

           

          Tried all my USB 3 ports

          I have checked all USB power settings

          Disabled all gaming overlays

          Checked for physical damage on Oculus Link cable

          Repaired the Oculus PC Application 

          Tried using Public Test Channel on the Oculus PC Application

          Provided support logs using OculusLogGatherer.exe

           

           

          and then some...

           

          Reformatted My PC

          Installed a PCIe 3.2 usb card

          monitored power / heat of GPU

           

          Nothing has had any difference and I can cause the issues 100% of the time just by playing Demeo from Oculus PC Application via Link. 

           

          Oculus support just keeps asking for video / pictures to get a better understanding of the issue. Capturing a screenshot much less video is almost impossible holding a phone up to the headset as they suggest.  I have gave support a direct link to this thread and just feel like they are giving me the run-around.

            I submitted a ticket through support ("email us"). I strongly suggest to anyone having this issue to do the same, for them to collect a maximum amount of informations on the issue.

            I can confirm that v31 doesn't solved the issue. I've also tried clean install of Oculus Desktop app without touching Debug Tool and... guess what... white stripe is still there. 😕 I have no problem in Project Cars 2, but in Dirt 2.0 it appears sooner or later every time. GPU overheating is definitely not the problem.
