Re: [Lynx-dev] lynx blinking after terminal window resizing
Hi, did this make it into the fixes? I get the same behavior inside tmux which is linked to ncurses. I don't see the flicker in terminal if I use it outside tmux (like directly in WezTerm). Also as a side note, I don't see lynx reflow the paragraphs when winch arrives, even if NONRESTARTING_SIGWINCH:TRUE is set. links and elinks both reflow. Is there a good reason to not support winches? Thanks, Robin

Re: [Lynx-dev] lynx blinking after terminal window resizing
The same blinking (screen flicker) being talked about happens on my machine too, after screen resize. macOS 12.5, xterm-256color for lynx inside tmux, iTerm2, aarch64 (apple silicon), lynx version: current (latest).

I'm reproducing this on Fedora 36 with distro-supplied packages (xterm-371-1.fc36.x86_64 lynx-2.9.0-dev.10.2.fc36.x86_64 ncurses-6.2-9.20210508.fc36.x86_64).

Re: [Lynx-dev] lynx blinking after terminal window resizing
Here is steps to reproduce. Alpine edge, x86_64 Sway wm 1. Open foot terminal in float mode. 2. Run `lynx github.com`. 3. Change foot into fullscreen mode. 3. Try to jump between the links. 4. See blinks. Here is my lynx config: http://ix.io/46wb Here is video demo: https://0x0.st/oe2h.mp4 How can I help more?

Huh.
>The blinking that you're describing would be full-screen repainting.
Yes. I can verify that it does that in a typescript (attached).
I started lynx in an 80x24, moved the cursor down and up twice,
resized to 80x25, pressed ^R, then moved the cursor down… thrice,
I think. The pagetitle shows up several times, matching repaint.
$TERM is xterm, it happens with GNU screen as well (TERM=screen,
not the Debian “ncurses-term” madness of screen.xterm or so, as
that breaks sshing into BSD boxen).

Hm. I’m attaching my /etc/lynx/local.cfg and /etc/lynx/lynx.lss and
~/.lynxrc files, maybe then? And ~/.Xresources as well…

The blinking that you're describing would be full-screen repainting. When I resize the screen and press ^R, subsequent cursor movement is only updating the expected link-highlighting characters.

Perhaps this would be reproducible if the version of lynx were identified,
as well as which platform. I don't see it using
- xterm 372,
- ncurses 6.1 and 6.3,
- lynx 2.8.9rel.1 and 2.9.0dev.10

I tried to make a screencast, but you cannot see it there. I was able to somewhat spot it on a video I made with a smartphone camera, but any attempt to bring that into a size that can be mailed hide that again.
