I've seen once similar maxing out of a cpu after ~30s. Turns out the cause was a stupid typo I had made in some scheme code (starting a comment with : instead of ;) and which surprisingly was not triggering any visible error.

I'm not suggesting you made the exact same typo, but it could be worth trying to run texmacs with a fresh blank ~/.TeXmacs folder (just rename it before starting texmacs so as to preserve your settings).

Same symptom as the closed #36714:
after a short while, texmacs.bin brings one CPU to 100%.

Installed version 2.1
SVN revision      13558
from http://www.texmacs.org/Download/ftp/tmftp/generic/TeXmacs-2.1-C.tar.gz
System: openSUSE Leap-15.3

But this "one cpu at 100%" was also present with 1.99.17.

To reproduce:
export TEXMACS_PATH=/usr/local/build/TeXmacs-2.1-x86_64-pc-linux-gnu/TeXmacs

In the empty document window, type "a" then <ENTER>   (mandatory to see the cpu increase)
wait about 20 s
(time measured today, repeatedly, but it might have been longer some other days).
Besides, Preferences > Others > Automatically save
is "Disable", so it does not look like an autosave issue

Note: every time texmacs is launched from the terminal,

Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 72: non-double matrix element
Fontconfig error: "/etc/fonts/conf.d/10-scale-bitmap-fonts.conf", line 72: non-double matrix element

X Error: BadDrawable (invalid Pixmap or Window parameter) 9
  Major opcode: 62 (X_CopyArea)

TeXmacs] With linked TrueType support

I'd be ready to perform more tests, with some guidance, if you wish.
