It was the wxt terminal (which I normally use all the time).
I'll do more tests tomorrow since I can't reproduce the problem
remotely (or locally on a different machine).
I could also look at the strace and xtrace output.
When I got the problem, using FVWM's Delete command to remove
the window did not have any effect (so this is not just a
display issue, the process was frozen in some state); FVWM's
Destroy command worked. These commands are described as follows:
Delete
Sends a message to a window asking that it remove itself,
frequently causing the application to exit.
Destroy
Destroys an application window, which usually causes the
application to crash and burn.
The problem occurred first at 2024-02-28T19:12:24 CET.
At that time, journalctl shows:

(and nothing else in the previous minutes and the next minutes).
But I could see that there was exactly the same thing with a previous
invocation a few days earlier, using gnuplot 5, which had no issues.

I think I'll be able to do the bissect.
