    I get similar problems using cameras with electronic viewfinders after
    decades of optical ones. I suspect it's not the absolute lag that gets
    noticed, but the offset between when your fingers do something, and the
    signal reaches your senses.

    I refuse to give up on my dSLRs because light goes through the optics
    in 2 nanoseconds while the screen is milliseconds later. Since the
    camera companies dropped dSLRs I have dropped out of buying their
    equiptment.

    According to MitchAlsup1 <[email protected]>:
    I am convinced that quantum computers will eventually be good at some
    things that regular computers are not and cannot be. ...

    They seem to be rather exceptional at protein folding compared to
    classical computing.

    I think you're confusing them with recent large AI models. They run on
    normal computers.

    The way I implemented it was by updating the "official" back frame buffer, and compare the update with the visible front buffer. If at any time a write to the back buffer did not result in something that was already in the front buffer, I just copied the back buffer to the front and went on from there.

    The only application I use which is still doing something like it
    nowadays is `mosh`, and I must say that it is a great feature.
    [ It's occasionally "problematic", such as when I type a password before
    the prompt appears, so `mosh` doesn't know yet that it shouldn't be
    displayed. 🙂 ]
