Okay. That experimental.refresh-app-awareness did not fix it.
This morning (16 March), while switching tabs, the font "change"
occurred visibly again. Apparently I'm not looking at a fresh Chromium.
Yet still there is _something_ that messed up the fonts.
Here's some system info:
$ snap list --all chromium

So, apparently there _are_ two chromiums running at the same time. Not
sure why, but that might explain conflicts. The old one was branched off
a --password-store parent.
Looking at the age in the fontconfig dir:
$ ls /var/snap/chromium/common/fontconfig/ -ltr
total 1700
-rw-r--r-- 1 root root 151 mrt 2 15:39 fonts.conf
-rw-r--r-- 1 root root 408 mrt 2 15:39
34e0e5ac-5c62-4453-a219-f92185a510d1-le64.cache-7
...
-rw-r--r-- 1 root root 104 mrt 2 15:39
34e3ea57-0766-47d7-ac34-3152aff3ab1c-le64.cache-7
-rw-r--r-- 1 root root 152 mrt 2 15:39
2bdf00a0-773f-43e6-bc52-f8023b64a749-le64.cache-7
So, all files are from the same date and not recently changed or
something.
Steps I did now:
- $ sudo rm /var/snap/chromium/common/fontconfig/*
- fonts were still bad
- stopping chromium (alt-4)
- observe how the old chromium is still running:
$ ps -ho lstart,command -p $(pgrep -f chromium | tr '\n' , | sed -e 's/,$//')
| awk '{print $2 " " $3 " " $6 " " $7}' | uniq -c
1 Feb 11 /snap/chromium/1899/usr/lib/chromium-browser/chrome
--password-store
3 Feb 11 /snap/chromium/1899/usr/lib/chromium-browser/chrome --type=zygote
- start chromium again
- fonts are good again
I'm killing off the old chromium/1899 now:
$ kill 965195 965392 965393 965395
(Where the parent 965195 refuses to die without SIGKILL.)
Restarted chromium again, for good measure.
$ ps -ho lstart,command -p $(pgrep -f chromium | tr '\n' , | sed -e 's/,$//')
| awk '{print $2 " " $3 " " $6 " " $7}' | uniq -c
1 Mar 16 /snap/chromium/1926/usr/lib/chromium-browser/chrome
--password-store
3 Mar 16 /snap/chromium/1926/usr/lib/chromium-browser/chrome --type=zygote

--type=utility
9 Mar 16 /snap/chromium/1926/usr/lib/chromium-browser/chrome

Observe that the fontconfig directory is empty at this point (even
though chromium has started twice after purging it).
Now wait for the issue to reappear...
