Excellent article.

I do not have the same technical depth to dig this far as the author, but this kind of problem seems pretty common on laptops, especially those with "switchable" iGPU/dGPU setups.

I had an Acer laptop about 7-8 years ago with almost the exact same latency symptoms. In the end I just disabled the dGPU in the BIOS (since I only used it for office work), and that instantly solved the issue.

This kind of thing is very infuriating because not only is it hard to track down the root cause (which I am very grateful the author did), but it is also even harder to get the vendor to actually acknowledge or fix it.

I'm more bothered by the fact that this reference image is clearly a well-made piece of digital art by some artist.

We all know the questionable nature of AI/LLM models, but people in the field usually at least try to avoid directly using other people's copyrighted material in documentation.

I'm not even talking about legality here. It just feels morally wrong to so blatantly use someone else's artwork like this.

I see where you're coming from, but I disagree on some specifics, especially regarding bytes.

Most people care about the length of a string in terms of the number of characters.

Treating it as a proxy for the number of bytes has been incorrect ever since UTF-8 became the norm (basically forever), and if you're dealing with anything beyond ASCII (which you really should, since East Asian users alone number in the billions).

Same goes to the "string width".

Yes, Unicode scalar values can combine into a single glyph and cause discrepancies, as the article mentions, but that is a much rarer edge case than simply handling non-ASCII text.

The biggest news is not what software they use but they finally moved away from mail list, which is a big win.
