Hi,
I'm using emacs master branch in terminal (alacritty). When moving
cursor with relative line number enabled or scrolling up/down, I
get
unpleasant screen flickering. However, frame switch works fine,
which
I suppose uses full rendering updates. It seems partial rendering
update doesn't work well. The author of alacritty mentioned one
possible cause : "flickering is typically caused by a program not
writing full updates to the pty. We drain all available bytes up
to
like 64k before yielding for a render. It may be that we should
add
some heuristic around time to prevent flickering from poorly
behaved
terminal applications." So my question is, can I enable full
updates
for every redisplay? Thanks!
Here is a screencast of flickering.
