That screen is terribly slow, even by e-ink standars. "Canvas" displays, developed by reMarkable and commercialized by Onyx, have a minimum lag of about 25ms (for writing) and a rendering mode call "A2" that makes it user interaction quite fast for e-ink,[1] serviceable even for watching video [2].

IIRC Canvas displays were not developed by reMarkable, it just uses one. But one of the key selling points was that the reMarkable didn't use the vendor display driver for that Canvas display, but instead they wrote a faster one. I have some Canvas-based devices and the screen lag varies quite a bit (the reMarkable screen is faster).

  As I understand it, reMarkable claims[1] to have developed CANVAS from the ground-up on top of Carta technology, in close collaboration with E Ink. It may be as you say and they developed just the drivers, but I believe from their press releases that they are responsible for some breakthrough detail to accelerate refresh, that E Ink didn't think was possible (something to do with a waveform transmission signal to transfer pixels to the screen). They were the first to build the technology to bring refresh times for writing near the 50ms mark, and hold the patent about it (AFAIK they license this patent to other builders who use Canvas).

    Ah yes I mixed up CANVAS vs. CARTA! So my other devices actually have non-CANVAS e-Ink Carta displays.

      I own a reMarkable and a Boox Nova Pro with CANVAS, writing speed is the same but reMarkable's software and feel is definitely better (though I suspect a matte screen protector on the Boox would make the drag feel almost the same).

Worse, the video in the article appears to be sped up.
