Wahat exactly do you mean with “text mode”? Which terminal are you using,
and—most importantly—which font?

So not only in text mode (i.e. TTY or terminal)?

See it where? A (small) screenshot may help.
Perhaps it is an overwide character, but the program that displays the text
wants to adhere to a regular character width. I’ve had this issue in the
past with Konsole.

Only the gear? Or also all the other symbols in the video player toolbar?
Again, a nicely cropped screenshot may shed some light so we can better
understand it.

Did you set up a strange or very unusual DPI value for your font rendering?

First of all, thank you for replying to my question.

By "text mode" I mean that "it happened in Gvim, in a web-browser
and in a dialog-window for saving files" but not in videos or pictures.

> Which terminal are you using, and—most importantly—which font?

I am using xfce-terminal, and it is using Monospace Regular font on 11 pt.

In Gvim, I use the same Monospace Regular font on 10 pt.

I do not know which font is in use by the window that helps me
to save html files from the web-browser.

I have noticed this problem with cyrillic symbols and dots.

No, as I already explained above, by "text mode" I mean that
"it happened in Gvim, in a web-browser and in a dialog-window
for saving files" but not in videos or pictures.

Unfortunately, I have not made a screenshot of this. So, I will try to
explain:
When I press Ctrl+s to save an html page from the google-chrome
a dialog window is opened with the suggested name of the file that
ends in "html." There is a dot before that "html" but sometimes it was
not shown to me. The same was with the top parts of some cyrillic letters
(to the point that it was hard to read).

I do not think that it was connected with overwide characters because
the effect appeared not with them or beside them.

This problem with dots and top parts of letters *faded*
after I updated the freetype package this Sunday.
However, I cannot say that it stopped immediately after this update.
It indeed *faded* during a few rebooting after that.

No, not only the gear symbol but some other ones as well, but not all of
them.

I was able to reproduce it just now and made a few screenshots.
I will add "a nicely cropped" ones as attachments to this email.

It as also interesting that the symbol in the youtube player toolbar
that was shown only partially changes to the full one when I move
a mouse pointer over it.

No, I have not played with this. And moreover, with the same settings,
it was completely ok for years.

It probably should be added that instead of that dot I saw a white space.

I see, you mean text that was actually rendered and not part of an image.

I noticed that those applications you mention are all GTK-based. Do you have
any available that are built on Qt (or any other toolkit)?

I can’t say that I have seen that youtube issue before. But I also have no
idea what it could be or how to solve it. Could you create a new browser
profile and check whether the issue is still present there? This could tell
us whether it’s an issue with your existing profile.

Yes. Thank you for replying to this thread once more.

Yesterday evening I finally managed to catch the problem
with incomplete rendering of cyrillic letters "in text mode"
and make a screenshot of it. This time, it happened in
html page that was open in google-chrome.

A properly cropped screenshot of it is attached to this email.

As it may happen that you and other readers of this thread
are not familiar with cyrillic letters to the extent needed to see
that they are rendered incomplete, I also add a screenshot
of the same text rendered complete. I made it this morning
with the same google-chrome.

By the way, this means that the problem appears from time
to time and does not look to be easily reproducible.

I even assume that it may be a hardware problem
as my computer is quite old, but unfortunately
can not check this assumption so far.

> I noticed that those applications you mention are all GTK-based.

Yes, I try not to mix GTK and Qt on this old computer
as much as possible to reduce the time needed
to update the system. So, most of the applications on
it use GTK. The only one that I know uses Qt is VLC
as it does not work properly with GTK. However, I use
it quite rarely.

> Do you have any available that are built on Qt (or any other toolkit)?

I am afraid that VLC is the only one.
Once tried Qutebrowser was removed a long time ago.

I will try to create a new user and run google-chrome from his profile
and report the result here.

However, when the disk with my /home directory
was for a few months installed on another computer
also runned by Gentoo with similar configuration
I have not noticed such problems.

Moreover, I am starting to suspect that
the problem with incomplete rendering letters
"in text mode" and the problem with symbols
in the youtube video player toolbar may be
separate ones as the latter is much more
reproducible and appears only in google-chrome
(have not noticed it in Firefox, for example,
though I quite rarely use Firefox to view youtube videos).

I can't offer much help on this, but I'll share a similar experience. I have
seen something like this happening on Chromium, running on Enlightenment
desktop a few years ago. I recall it was affected by the scale set on the
desktop 1.2:1 or something like that. I can't recall if this was also
occurring on Plasma. I think I saw the same missing character problem on the
title bar of the browser window. This was on English text (UTF8 encoding).
Firefox and other applications didn't have a problem. At that time I recall
Chromium's rendering of the menu/toolbar and window border was fighting against
the desktop. Some update on Chromium eventually fixed things. So I blamed it
on the interplay between the desktop, browser and graphics card/driver
(radeon).

Thank you for your input. My graphic card is also Radeon,
namely, built-in ATI Radeon X1250, and I use Awesome WM.
The problem appears mostly in google-chrome, but I saw it
also in Gvim, and currently it appeared also in the taskbar.
A properly cropped screenshot is attached to this message.

I suspect some interaction between your window manager and graphics driver
causes your character and symbol rendering problem. You may want to install a
different window manager and see if the problem remains, then approach the
Awesome devs to help you with troubleshooting. It's not unusual for less
mainstream WM devs to focus their code on NVidia/Intel, or whatever hardware
and drivers they have at their disposal and miss out on such problems like
yours until they are drawn to their attention.

Thank you. I will try another WM, probably XFCE4, which
I have used before Awesome (among other options)
and report my finding in this thread.

Today, I emerged xfce4-meta, started XFCE4
and spent a short period of time within it.

For this short period of time, the "problem"
with rendering symbols in youtube video player
toolbar in google-chrome appeared in exactly
the same way as it appeared within Awesome WM.

I have also noticed the problem with rendering
letters in google-chrome. However, it appeared
a bit different: parts of letters in an html page
were closed by small black boxes, however not
everywhere but only on a side panel.

At the same time letters of a word written on a button
had exactly the same rendering problem as within
Awesome WM.

So, it seems that the problem is not specific to Awesome WM.

It seems to me that the problem is somehow related
to redrawing a frame. However, I am still not sure if
it is a problem of software or hardware.

I have not tried another google-chrome profile so far.

I would create a new (temporary test) user and log on with that. If the
problem still persists, it’s either a system config, a library (cairo,
freetype et al, graphics driver) or maybe even a hardware issue.

Yes. It is exactly how I intended to do this, and sorry for not having
done it yet.

However, I have found that the problem of the incomplete rendering
symbols in text mode appears only after I play youtube videos in
google-chrome and persist after exiting it.

Playing youtube videos in firefox-bin does not cause this problem to
appear, nor does running google-chrome without playing youtube videos
in it.

Moreover, in Firefox-bin, I even do not have the problem with
incomplete rendering symbols in the youtube video player toolbar.

So, I already can blame this problem completely on google-chrome.
Moreover, I already know how to avoid it. :)

P.S. My current version of google-chrome is 101.0.4951.54. However,
the problem already appeared in its earlier versions and has survived
several updates of the google-chrome.

Here I was wrong: running google-chrome even without playing youtube
videos may cause the same problems with incomplete rendering of
symbols/letters in text mode.
