i have the same problem - oculus told me to check and do the following - still didnt work though , but here's what they said
Windows 10 Build 18363 is quite outdated. Please c install the latest version which is 19041.
Nvidia Overlay is enabled and should be disabled. You can do this by using these steps:
Click on the System Tray to show hidden icons.
Right-click the Nvidia icon.
Click GeForce Experience.
Click on the Settings icon.
Toggle "In-Game Overlay" to off.
Close the GeForce Experience window.
Publict Test Channel still shows disabled. Please ensure you're enrolled in the PTC from Oculus. This will keep your Oculus drivers up to date and the latest version will always be updated to you as soon as its available.
Ensure that USB power saving settings in Windows Device Manager are not enabled for your USB ports:
Right-click the Start button and open Device Manager.
Find your USB ports.
Right-click and select Properties.
Go to Power Management.
Make sure that options to save power are deselected (please note that it is normal that some of them will not have any checkbox for power saving settings).
Exactly te same is happening to me, first I thought It was my Laptop even when is a Dell g3 Gtx 1660 ti , i7 , 20gb ram, then i plugged the quest using the official cable into my PC , rtx 260, Ryzen 7, same thing, still shakes, I tried other software like quill and Tvori , they work fine. I tried the same as @PenelopeSaladfingers, also I adjust the resolution using the oculus debug tool and nothing. I am pretty sure this is not a cable or power related issue, this must be a Software issue . @OculusSupport Please Advice.
I just bought Medium a few days ago and ran into the exact same issue.
After trying a lot of different things from adjusting graphic driver settings to changing USB ports I finally managed to fix it today in a rather counterintuitive way.
It turns out that if Medium is launched through Revive (I'm using version 2.1.1) it works normally.
Revive also fixes the weird brush stroke jitter I was having in Quill.
As an added benefit I can now also use "Desktop+ OpenVR Overlay" to view reference pictures or watch tutorials while sculpting. So I would probably continue to launch it in this way even if they fix it. 🙂
