Hi Michal,
Thanks for advice, but unfortunately it did not help:
did 'caja --quit' sevrerl times, even with 'rm -rf ~/.config/caja' in
between...
No help.
It does not look that caja is main cause or/and Xorg, but
everything... I knom
top is not proper tool, but its name contains only 3 letters, so I
could follow

There are way too much syscalls for a presumably idle system,
about 10 times of the expected number.
May a truss -f -p <pid> on the high CPU processes could give
clue what they are actually looking for.
Hi all,
I have give it a try again. Created truss from 2 top processes:
* 2483 /usr/bin/python2.7 /usr/lib/time-sliderd
* 2494 /usr/lib/amd64/mate-settings-daemon/mate-settings-daemon

and it looks like fonts are re-reading in loops... Sometimes terminal
(mate in this case) reacts fast, then slows down till stop, then is
responsive again...
Also, this confirms loop:
$ grep -E "open.*fontpath" 2delete/LOAD.2484.truss | $awk '{print $2}' |
sort | uniq -c | sort -rn | head -5
6 open64("/etc/X11/fontpath.d/75dpi-ISO8859-15:unscaled:pri=26",
6 open64("/etc/X11/fontpath.d/75dpi-ISO8859-15:pri=96",
6 open64("/etc/X11/fontpath.d/75dpi-ISO8859-14:unscaled:pri=26",
6 open64("/etc/X11/fontpath.d/75dpi-ISO8859-14:pri=96",
6 open64("/etc/X11/fontpath.d/75dpi-ISO8859-13:unscaled:pri=26",
$ grep -E "open.*fonts/" 2delete/LOAD.2484.truss | awk '{print $2}' |
sort | uniq -c | sort -rn | head -5
4 open64("/usr/share/fonts/X11/util",
4 open64("/usr/share/fonts/X11/misc-ISO8859-9",
4 open64("/usr/share/fonts/X11/misc-ISO8859-8",
4 open64("/usr/share/fonts/X11/misc-ISO8859-7",
4 open64("/usr/share/fonts/X11/misc-ISO8859-5",
(I have stopped truss, so number of open commands depends on very moment
I pressed Ctrl-C)
If someone is interested in truss files, let contact me.
Thank you for your responses/ideas...
With best regards.
