If you move to the end of a truncated line in the package list, part of
the previous screen will be retained when it should actually be
invisible.

To reproduce this problem, start emacs -Q, select the entry "news" from
the package finder (the command finder-by-keyword), then turn on
truncate-lines (if it is not already on) in the package list containing
results from the finder, resize the window showing the package list so
that lines are being truncated, and move to the end of a truncated line.

This problem is not present in Emacs 27.2, and cannot be reproduced on a
TTY frame.

Parts of the previous content of the display will be preserved, which go
away upon invoking redraw-display.

Correction: I meant to say "which should be".

I don't think I can reproduce this here, at least not in "emacs -Q".
But it's hard to say because you didn't tell which part(s) of the
previous contents I should watch, and there's a lot of stuff on the
screen to be sure that none of it was left behind.

So please describe the recipe in more detail:

  . to what width to resize the frame
  . how do you "move to the end of a truncated line"
  . which parts of the display are left on the screen

Thanks.

Sorry for that.

> So please describe the recipe in more detail:

80 (character width) seems to be sufficient.

>   . how do you "move to the end of a truncated line"

By moving to the line, and calling move-end-of-line (C-e).

>   . which parts of the display are left on the screen

Parts of the names; I've attached three screenshots, of which
"before.png" depicts the package list before the bug is triggered,
"bug1.png" depicts the bug, and "correct.png" depicts the screen after
redraw-display.

Thanks.

That's list-packages, not finder-by-keyword.  I don't see the problem
in the latter, but I do see in the former (and in other displays that
use tabulated-list-mode, for example "C-x C-b").

I will look into this, thanks.

My bad. Thanks.

Thanks for looking into this, Eli.  It's greatly appreciated.
