I’m not sure what the bug is, but this is a terrible fix. What this is doing is forcing the WindowServer to composite the cursor rather than treat it as a hardware overlay. I suppose the issue must be pretty bad for OP if this helps, but … ugh.

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.

linux was plagued for a long time by lagging mouse cursor

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?

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.

This was an Nvidia driver thing from the bad old days of Nvidia driver issues, I think.

I have always had much cheaper Intel GPUs and not seen it (except in the very very old pre-GPU days, 30+ years ago with the odd badly behaved X app)
