I have been using emacs-lucid as a server for a few months & encountered
repeated sporadic annoyances. What follows is somewhat vague because I
cannot give a precise repeatable sequence of operations which lead to the
particular fault. Nevertheless, what I describe has occurred on far too
instances. The machine is a Lenovo P15v Gen 1 with an i7 8c/16t CPU using
Intel UHD graphics. I have Slackware-current on one partition & Fedore 34
on another. While this report is from the former, the *identical* results
happen on the Fedora machine. Furthermore, it makes *no* difference whether
it runs in console or xterm.
Launch emacs as a server. A buffer has a bash or elisp script with
font-lock-mode enabled (syntax highlighting). It looks just fine. Then, I
switch to another buffer & when I return, part of the file is not visible.
Close inspection shows that only text encoded as strings is rendered
black-on-black or white-on-white. Disabling font-lock-mode shows nothing is
missing! Again enabling font-lock-mode & the same text is missing. Killing
the buffer & reloading does not fix the problem. At this point opening any
new bash or elisp file with strings is futile. The only way to correct all
is a restart of the daemon! Of course, any setup of screens / consoles is
lost. However, no data is ever lost or damaged.
Here is the general scenario
tty1> launch a server
emacs --daemon
or
emacs --fg-daemon
or
emacs M-x server mode
tty2> run Midnight Commander
mc
navigate -> .bashrc (for example)
emacsclient -t .bashrc
tty3>
mc
navigate -> file1
emacsclient -t file1
navigate -> file2
emacsclient -t file2
.
.
.
Initially everything behaves as expected in console & X. Then on time
scales ranging from minutes to hours with the various emacsclients,
randomly switching among tty's & killing / loading buffers, I eventually
see that .bashrc is displayed with "missing" chars.
Attached are two screenshots (before & after failure) of my .bashrc from an
xterm.

Are they really missing, or just displayed with the same foreground
and background colors? What happens if you move the cursor (with C-f
or C-b) across the "missing" text?
Also, do you see any error messages in the *Messages* buffer when this
happens?

So it sounds like the faces lost their colors or something. When the
problem happens, what does "M-x list-faces-display RET" show for the
font-lock faces: do they appear in their normal colors?

Is this with a terminal Emacs or a GUI Emacs?

If this is with a terminal Emacs, could this be related to the face
terminal bug you fixed the other day in Emacs 28?

Unlikely: AFAIU, that bug only appeared once we switched to storing
faces in a hash-table, and only when clone-frame was calling that
code.

1) Using standard agetty, not emacs terminal.
2) M-x list-faces-display (after fault)
All OK *except*
font-lock-string-face (black-on-black)
sh-escaped-newline "
toolbar "
window-divider-last-pixel "
Expected this, of course. Note that once the fault occurs, it is permanent
(until the daemon restarted.). Any new files loaded into buffers exhibit
the same loss of string highlight.

Sorry, I read wrong. This is using emacsclient -t (terminal emacs).

I'm not sure I understand what this means. What is "agetty"? And
what do you call "emacs terminal"?

And what happens if you try to customize these faces to define the
colors they should have? Or different colors? Does that work, or do
these faces fail to display any colors, no matter what?
Btw, how many colors does this terminal support? You can find the
answer like this:
M-: (display-color-cells) RET
And finally, does "M-x list-colors-display RET" show some colors
incorrectly?

Linux console login utility.

emacsclient -t (terminal mode) as noted in original post. Not -c option.

8 : console
256 : xterm

It works! Tried it from the menu bar.

So it sounds like the faces lost their color definitions for some
reason?
When this happens, and you invoke "M-x customize-face" on a
problematic face, what does Emacs show for the color attributes of the
face in the Customize buffer?

Yes. Something overwrote the setting returning it to default state = black.

black.
I then entered green & voila, all was well.

OK, so please describe again, in as much detail as you can, what do
you do with Emacs between correct display and incorrect display. You
said you switch to another buffer and return, but could you tell more?
Just switching to another buffer and back immediately triggers that?
Or something else is needed?

That is indeed the tough part. I have yet to find a definite repeatable
pattern that induces the bug. But, I now usually arrive there in a few
minutes of activity with two emacsclients -t in use.
Switching back & forth immediately will not do it. At least one client is
loading / unloading various files before switching back to other client.
Take a look again at the original post for more of these general actions I
use.

So two frames from two separate emacsclients are always involved? And
you need to switch from one client to another and back?

Two tty's & emacsclients or more are used:
(In X org, I open 2 workspaces. Each has an xterm.)
tty1> emacsclient -t /home/rds (showing dired)
visit .bashrc (it has lots of strings from aliases)
switch to tty2
tty2> mc (run Midnight Commander)
edit .Xesources ($EDITOR=emacsclient -t)
It looks fine.
switch to tty1.
.bashrc looks OK.
switch to tty2
edit more files in my tree randomly with emacsclient.
switch to tty1. All OK? yes. back to tty2.
keep repeating this cycle. Eventually, tty1 will lose its string display.

It's strange that only some faces get redefined to use different
colors. Are all the problematic faces using the same foreground
color, and if so, what is that color on those terminals you are using?

Hm... you don't happen to have any packages installed that alters these
faces, by any chance? (Grep your .el files for `font-lock-string-face',
for instance.)

Very astute!!!
Found this in my init.el
(set-face-attribute 'font-lock-string-face nil :foreground "black")
Thanks.

I'm closing this bug report, then.
