I have noticed my M1 Mac Mini behaves a bit strangely when I have my external USB3 HDD plugged in. The mouse motion is stuttery, but unplug the drive and it is smooth as silk. There's evidently something low-level going on, probably USB error recovery.
Might be worth checking if you have any external hardware causing issues?
My main bug bear is my HP Z27 DisplayPort monitor disappears when it goes to sleep. Have to unplug/replug the cable to get it to come back.
That’s an old issue (also had it with a 2012 Mac mini). It’s interference from your USB 3.0 device/cable on the 2.4 GHz ISM band.
Potential ways to fix the issue:
• use a short USB 2.0 extension cable (like this¹ 6″/15cm one) to force the USB connection down to USB 2.0 (not ideal, but guaranteed to solve the problem)
• move the USB 3.0 HDD further away from the Mac mini and mouse
• try swapping out the USB 3.0 cable for one with better shielding
For more information about the issue, see Intel’s white paper titled USB 3.0 Radio Frequency Interference Impact on 2.4GHz Wireless Devices here².

I've had similar sounding issues with a keyboard, mouse, a couple of USB audio devices plugged in via a hub to USB 3 (nothing high bitrate like a USB drive). I need to unplug one of the USB sound devices to stop this if it happens. I think all these devices are USB 2.0 at best.
I've had that problem with the bluetooth mouse and an Intel Mac Mini. I've also had similar problems with a DisplayPort monitor. Perhaps it isn't M1 specific.

I have no external drives at all.
Well I do but , because they are usb and turns out for this brand new Mac that should be 'everything I ever need' apparently I need to buy a huge adapter sizing like 'half of this Mac' to make it work with peripherals.
It doesn't even have sd card reader, not even micro sd card reader. To 'save space' and for better comfort I believe.
Somehow raspberry Pi manages to boot from such device. I wish the Apple engineers knew about such amazing feature of micro sd card.
If they just could figure out how this hi-tech technology of booting from micro-sd cards works they could do amazing things like booting without a need for 'Another Mac'! ...
