Thanks, I will therefore close this bug.

It could be a bug, please file a separate report with the details, and
let's take it from there.

[Message part 4 (text/plain, inline)]

Starting from 'emacs -Q':

Inside *scratch* buffer:

 M-x load-theme RET tango-dark RET (More visible on dark 
 backgrounds.)
 M-x describe-face RET font-lock-comment-face RET

I use the custom interface to set `weight` to `bold` and [Apply] 
for this session.

 M-x menu-set-font RET

I select "Noto Mono Regular" (although it occurs with other fonts 
too)
at for example value 20. The font size does not change much.

Now I navigate to the first line, hovering on the "T" of "This 
buffer is
for ..."

Hold down C-f while most characters change their color after they 
are
left behind. I've recorded a video of this here:
https://streamable.com/0fald

Please note that this is the minimal reproducible scenario. I have 
this
issue on my main config in lots of places where bold fonts are 
used even
if the cursor isn't on them. This is the most reliable way to 
trigger
this behavior.

The issue also occurs with `cursor-type' set to 'bar'
