Picom core dump with 13.1-REALEASE-p5

Hello to all!

Today I upgraded to latest release of 13.1 and everything went smooth,
as always. The problems appeared when I just started using the
machine. Is a desktop with cwm as window manager and I also use picom.
Until now everything was fine, but now after just opening some
terminals the machine freezes and I have to do a hard reboot. When I
login I just see how the RAM (4GB total) disappears. I tried XFCE and
the the system is usable again. So I narrowed down to picom. (There is
a picom.core dump file, but I do not know if it is of use).

This is all the errors I could find.

So in "cwm.log" I have this

xterm: fatal IO error 35 (Resource temporarily unavailable) or
KillClient on X  server ":0"                 xterm: fatal IO error 35
(Resource temporarily unavailable) or KillClient on X  server ":0"

And this is from dmesg

pid 19272 (picom), jid 0, uid 1000: exited on signal 6 (core dumped)
pid 71681 (Xorg), jid 0, uid 0, was killed: failed to reclaim memory
pid 55696 (picom), jid 0, uid 1000: exited on signal 6 (core dumped)

I also attach the full dmesg and also picom.conf if it any use
(although nothing change from prior version).

Thank you for your help. I really need my machine back. And I also need cwm.
