Why is my Cursor lagging every now and then, also why is the Nvidia_dGPU waking randomly when its supposed to be sleeping???

Device Info:
IdeaPad Gaming 3 15ARH7, Ryzen 5 7535HS, RTX 3050 6GB, 16 GB RAM, 120 Hz (display is connected to AMD-iGPU)

Link: Video of the problem (OR) Video of the problem

  • This stutter occurs randomly. Occurs when opening the 'context menu' from desktop (right-click), opening 'power&battery' menu and 'display' menu in windows settings.
  • It occurs on any version, Windows 11 24H2, 23H2, 22H2. Tried different drivers (iGPU, dGPU, chipset, BT, WLAN, LAN, ...) and BIOS combinations & also did multiple Windows re-installations.

What fixes it temporarily:

-> Going into the safe mode (which then uses 'MS-Display drivers' and disables all 3rd party drivers) solved the stutter/lag problem shown in the video, it didn't occur anymore.

-> Disabling 'NVIDIA GeForce RTX 3050 6GB Laptop GPU' in 'Device Manager' also fixes the lags/stutters. I did not face it anymore after doing this.

I tried inspecting the GPU in 'HWInfo64', and I can confirm the GPU stays asleep (https://ibb.co/chFyC2sn) meaning Optimus is doing its job. I can also see the GPU waking for a split second without any reason which is not supposed to happen, it should be 0% (0W) all the time.

EDIT: I JUST FOUND THE PROBLEM IS REAL FOR MANY. IT WAS AWLAYS THERE AND NEVER GOT SOLVED PROPERLY. (I can confirm it because I have seen this on several dual-GPU laptops in the shops recently which when I reported to support & here was denied.)

    The problem happens/happened on both touchpad & mouse on both the laptops.

    I had 2 mouses (one of Dell and some other one), both of them have/had it when tested on both laptops.

    Also I have tried changing the refresh rates, didn't help.

    I don't have the old laptop with me because I gave it away in less than 2 years obviously due to frustration on those problems, sometimes I have to work a lot fast and this thing gets in my way.

    Edit: I just found some old post here mentioning similar problem that has affected a lot of device, it seems the problem was never solved in the first place (https://learn.microsoft.com/en-us/answers/questions/2749195/(partially-fixed)-intel-nvidia-laptop-freeze-probl)

    Hi ,

    Sorry for the error, I thought it was a problem with the Acer Nitro's mux switch. I thought it was the same issue.

    I even noticed a bug between the drivers, which is why, even with changes in Regedit, the drivers are different. However, as you can see, the solution presented by the Intel team didn't work for everyone.

    I did some research, but to find out, I believe you've tried most of the solutions presented.

    Thanks

    No MUX switch. Like I mentioned above with some references, I see a lot of dual-GPU configured laptops being affected.
