Reminds me of a fix I wrote a decade ago. My Laptop would sometimes start emitting a high frequency whine when on battery. I figured out it only happened when the CPU went into performance states lower than P2 for power saving.

So I wrote a bash script that auto-started on battery mode and then calculated a hash every few seconds. Boom, whine solved. Terrible fix, but I never measured how much battery it cost me, so it was... fine.

That reminds me a lot of this xkcd comic where a user depends on an application overheating when the space-bar is pressed.

Terrible fix but it's a fix that's minimally-invasive and addresses a bug that causes a disproportionate annoyance to the fix. I can imagine your cursor lagging is something that is extremely annoying over time.

I've been using Linux every day for the last 17 years, and that's the first time I'm hearing this.

I'm genuinely surprised.

The way you word it, it looks like a famous ubiquitous problem. Mind sharing any details?

My latest and greatest ThinkPad T14s Gen 6 likes to do it sometimes on cachyos, I can't nail it down from a KDE or hardware issue as it never does it while docked or a external mouse

I've also had computers with nvidia, amd (even back when it was still ATI) and intel gpu's, at least since 2006, and can't remember ever having an issue like this.

Not saying it's not an issue, but there is such an incredible amount of hardware configurations that linux supports, so it's a bit weird to say that "linux" in general has suffered a bug like this.

There was a time when it was quite bad, especially if using Wayland and under heavy CPU or I/O loads. I think this has mostly been solved now, but I do recall getting frustrated with the switch to Wayland because of it.

not necessarily ubiquitous, but you can encounter some issues with "lagging cursor" even today, if you use standard raspbian for example

> usbhid.mousepoll=0 > to /boot/cmdline.txt > This option was implemented to enforce a mouse polling rate of 62.5Hz which dramatically reduced the XWindow event system update rate in certain circumstances (oddball or "performance" mice can have update rates of 1000Hz, which is silly).

People are downvoting you, but my Linux machine always feels like my mouse lags a bit compared to Windows.
