Hi again Jim,

I haven't isolated this one yet, but I'm flagging in case it rings any bells for you -- I'm getting rendering-lockups with dart-mode when I enable visual-wrap-prefix-mode. I've checked a couple of other programming modes which seem fine. My money was on lsp-mode (and maybe lens display), but I've disabled lsp entirely and it still locks up.

I don't get a backtrace (with debug-on-error), but I can get this (when I hit C-n to see anything is happening, as the screen goes blank):

===

Debugger entered--Lisp error: (args-out-of-range 519 519)

line-move-visual(1 nil)

line-move(1 nil nil 1)

next-line(1 1)

funcall-interactively(next-line 1 1)

command-execute(next-line)

===

I'll keep trying to isolate it. So far my repo is "open .dart file, M-x visual-wrap-prefix-mode".

cheers, Mark

Great, thanks for checking. I've therefore merged this to the master
branch as 135da3556bb. Closing this bug now.

(Though of course if you find any other issues with the new
'visual-wrap-prefix-mode' code, just let me know and I'll try to fix it.)
