settings is at 120 hz, but cursor is moving like its 40 hz(a bit stuttery behaviour) or something. I always use to have it at 60 hz, but now I want to change to 120hz. then this happen. I either have to restart windows once more or go in and change to another hz then it is normal again, so I have to change back again to get 120 hz.
never encounter this behaviour before.

windows 11
32 gb ram

Looks like it only happen at 120hz, when I let it stay on 60 like I used to, then it looks like this does not happen. Maybe I Am a bit early on reporting this. but I started the pc now and it was no problem(I changed it yesterday evening).

When auto refresh-rate change is enabled, MC (or MadVR) will change the rate to match the movie being played, often 24hz. It then sometimes fails to switch back to the original frequency when the player is closed (or crashes), leaving the screen at a low frequency and making the mouse jumpy like that. If you minimize the player during playback the frequency is also not reverted because the playback is still going (even if paused). So during video playback, jumpy mouse is expected.

Check the display OSD to check the actual current refresh rate. On some Windows display drivers, pressing CTRL+ALT+F8 reverts the display mode/freq back to normal.

Graphics may also be reverting back to a lower/failsafe frequency if the cable transport can't support the needed bandwidth and has too many transmit errors. Try a better HDMI cable.

Yeah, I know about that, happens sometimes. This is different...this is when I start my PC and use my mouse and the cursor does not follow evenly, it stutters a bit, everything shows 120 hz..but something does now communicate properly and give this result. I check that everthing is ok, I check tv is showing 120hz with the remote and np and windows settings too. all is 120 hz. so then I have to change hz fourth and back in windows displaysetting. Yes during movieplay cursor is jumpy and normal. This is on a lg oled b1, not monitor.

I just started it now and now it was ok. I highly doubt it is my hdmi cable which I only hva good experiences with and I know Supra follow 4k 120hz, 48 gbps, tried to use other but always go back to the one I use now. I have to see if this happens the next couple of times..

I think when it happened I also saw some delay when selection some settings in Win setting..when I manouvered around I saw one or two times that OS did now follow properly when clicking on some of the settings.

I will have to see if this is settled now, in the days to come.

reinstalled nvidia driver 560.94 using ddu in safemode ..and the rest of the procedure. still I have to always start windows and then start it again to get correct the issue or change hz and then back again on inital hz only then will this be resolved. maybe I yet again have to reinstall win 11.

this happens on first startup. So everytime I have to do a second restart then it is normal and not stuttery. or just change to a new hz and then back again, then it is normal again.

This doesn't seem related to MC at all. There are many people with this issue, here's a couple of solutions:

Some more:

Some people say a good mouse works, other say a cheap one is better for them; some say to uninstall the Logitech software; there doesn't seem to be a common fix for all.
