It should be possible to avoid this in VM. AIUI it’s a result of doing
coding system and base64, quoted-printable decoding on displayed text, which
will always cause a redisplay flash if the relevant text is being shown.
(Text is inserted, more text is deleted). It would make more sense to
do all the decoding somewhere that’s not being redisplayed, and only show
the text when the decoding is finished.
I’ve tried this a couple of times--I see the problem too, but its not as
much of an issue on the TTY builds I normally use, of course--but I haven’t
had much traction, unfortunately.
Yes, I guess that's what I mean. On 21.5, it is very visible, and
very
annoying - even on a tty frame, even on a very fast machine. On 21.4,
it's not visible at all on any machine I use, as far as I can see, so
I don't know whether it even happens.
I suppose I could put them under xscope to see what's actually
happening to the window!
