Earlier quoted context omitted.

guard is an inverted if statement, with the additional requirement that the branch must exit the parent scope. It's useful sometimes for readability, particularly for avoiding the "pyramid of doom" when you have a lot of preconditions that need to be checked: if fooOK if barOK { if bazOK { // do something } } } can be written as: guard fooOK else { return } guard barOK else { return } guard bazOK else { return } // d…

Already in 1963, the language CPL introduced "unless ... do ...", besides the "if ... do ..." inherited from ALGOL 60. Perl has just followed the example of CPL and BCPL, decades later. Using "if" or "unless", whichever is more appropriate, is far more readable than "guard". Moreover, there are many languages where an assignment or an initialization can appear in any place where an expression can appear. Such general…

You’ve missed (or ignored) the “compiler enforces leaving the scope” part.

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

still does for me

whenever the CPU works hard my cursor starts to lag

ah yes, the famous mac "Just works" OS

I think this ^ and the "Steve in his grave" comment should be a red flag for Apple execs.

Being flawless and polished at UX, hardware experience, and CX in general are the core of Apple's identity and revenue. Granted, the "hold it like this" thing was a huge gaff.

I also think the Neo is a culture miss that is diluting their brand. Their logo is synonymous with "expensive" and "quality" but the Neo is affordable and now it has cursor stutter.

But at the moment when it lags the system switches from hardware cursor to software cursor (CGCursorIsDrawnInFramebuffer() goes from 0 to 1) so maybe that transition is stalled somehow on Macbook Neo. With the disclaimer that I have zero knowledge of the MacBook Neo hardware, but I do know a bit about GPUs in general (including having written some GPU-accelerated drivers for Windows and the associated cursor-handling…

>A software cursor is manually drawn by the graphics stack, which saves what was under it, draws the cursor, and then whenever it needs to be moved, writes the original data back, saves the data at the new position, and then draws the cursor there.

AFAIK this hasn't been true for a long time on most platforms, certainly on macOS. The desktop image is composited on the GPU by assembling the underlying windows with appropriate effects like shadows and scrolling/scaling. A software cursor is just another overlay which may also have a transparent shadow.

Actually preserving what was under the cursor and putting it back is the sort of thing you wouldn't do anymore, because that's a cache which requires babysitting based on everything that's underneath and around it.

e.g. On macOS there's full screen zooming for accessibility, and if you wiggle the mouse, the cursor grows in size briefly (maybe even too big for hardware cursor to support).

I'm on a NEO right now, my Chrome has like 25 tabs open. Doom Emacs running in terminal, Obsidian open, Apple Music, Apple NOtes, etc. I have a lot open...

AND I'm not seeing this issue. What am I missing?

I'm on 26.4.

:shrugs:

EDIT: I guess I wait to update and install the latest version? Maybe the linked page could have stated there's a new regression in newer MacOS versions that introduced this?

is any one here using the neo for any coding work ? how is it ?

Not real work. It's an amazing couch laptop, though. I do have a full CLI tooling pipeline setup, though. I mostly read, research, and write on it. Chrome tabs galore open, Obsidian, etc...

It's pretty amazing at the price point. Thought last year the M4 Airs were on sale for $749 -- I'm doubtful we'll see that price again on those....

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

Before reading the background info, I was going to recommend a much simpler fix, but they actually already mention it in there: "Also the mouse cursor size can be changed."

This was going to be my suggestion because it also fixed a similar CPU/GPU related issue many years ago: Apple's own TV.app would have minuscule color handling differences whenever subtitles would show during a movie. This was driving me nuts while showing a moody black & white film for a movie night - every time a subtitle would pop up, the entire scene's black levels would shift slightly (and it wasn't any kind of adaptive/localized brightness or anything like that, it was the actual rendering).

Some online sleuthing revealed it was GPU related (pure GPU video decoding vs. the CPU overlaying subtitles on the screen), and that bumping up the cursor size (even the tiniest amount) in mouse settings would fix it. It worked.

It's barely noticeable, but I actually prefer the slightly bigger mouse cursor now anyway, so it's part of my standard macOS setup.
