External monitor is extremely laggy after updating nvidia proprietary drivers past 550.144.03 #55282
Description
My laptop is a Lenovo Legion 5 and it has that dual graphics card setup with an Inter iGPU and a discrete Nvidia GTX 1650. (I'm sorry.) This problem only happens when I:
- Select "dynamic graphics" from the BIOS
- Update nvidia proprietary drivers past the version 550.144.03
- Select my external monitor as the only active display.
- Use Xorg (I don't think Wayland works in the "dynamic graphics" configuration yet)
When these conditions are met, the video output becomes extremely laggy. I am currently on KDE Plasma but this happens with i3 as well. The cursor moves fine at 144Hz. But everything behind it, every window, the Plasma toolbars and such run at something like 0.5 frames per second.
For years this laptop has been working great. This has only started happening after updating nvidia past the specified version. The output is smooth if I use a multimonitor configuration like "extend display" or "unify (mirror) display". If I disable "dynamic graphics" from the BIOS and only use the dGPU, using only the external monitor works fine too.
I have tried searching for a fix for this but it seems like no one else is having this problem.
I had -m hold those packages for a couple of months hoping that some nvidia update might magically fix the problem but that didn't happen unfortunately.
I will dump some info that might help with the diagnosis:

I am not sure where to start looking to find what the problem is.
