Mouse cursor disappears on half the screen

[Felensis]

ISSUE
When changing the Valve Index HMD refresh rate via SteamVR video settings the mouse cursor starts disappearing on half the screen over its whole right side starting from the center. This issue also occurs by simply starting SteamVR without any further user interaction while the Index is connected to the PC.

OS
Windows 11 Home 23H2 Build 22631.4317

GPU
NVIDIA GeForce RTX 4070 Ti SUPER (MSI GAMING X SLIM)
Game Ready driver 565.90
Also tested with GRD 561.09 and 560.70 which are also affected by this.

STEPS
Connect Index HMD to PC
Start Steam
Start SteamVR (tested with 2.5.5, 2.7.4, 2.8.4 beta and 2.8.5 beta)
Open Steam VR settings
Open Video settings
Change refresh rate for Valve Index HMD (selected value doesn't matter)

RESULTS
Mouse cursor immediately disappears on screen starting from its center over the whole right side of the screen.

EXPECTED
Mouse cursor stays visible no matter what video settings I change for my Valve Index HMD.

WORKAROUND
When temporarily changing the display refresh rate (not Index refresh rate) then the mouse cursor comes back. Alternatively restarting the video driver via ctrl+win+shift+B works also.

Same

I am also having this issue. Steam VR makes the mouse cursor vanish on the right side of the screen. I only have a single monitor. I am on an Aurora R16 running an Nvidea RTX 4060ti.

I have same issue. RTX 4090. Newest drivers. I did not change refresh rate, this just happens when I start Steam VR. It persists even after closing Steam VR. Mouse cursor is invisible on exactly the right half of my display. I am using Windows 11.

Likewise. nVidia 4090 Windows 11 HTC Vive Pro 2 mouse cursor loss occurs immediately after opening SteamVR requires a sysstem restart or a video driver reboot to recover the mouse cursor.

I have the same issue, it started after I got a second monitor. I'm surprised there's no actual fix for this yet. Interesting the cursor does work in steam VR, just not on my monitor.

Exact Same issue every boot of Steam VR - RTX 3090 i have to reset drivers each time. Even closing all steam and vr serve processes does not fix. Re starting video drivers does work but only after steam VR closed. Currently on 2.8.8 as latest steam VR beta causes CDTs every time i boot some games
