gllines_jgl2_@<. 1 2 3.3
will execute as
gllines_jgl2_ 01
gllines_jgl2_ 2
gllines_jgl2_ 3
which is an error.
gllines_jgl2_@:<. 1 2 3.3
will execute as
gllines_jgl2_ 1 2 3
which is what was intended.

see the prototype of gllines in previous email.

Replace @ with @: worked.
Any theory why it crashed with @ ?

so that it expected integer array but a floating point data type was
fed. JE should either signal a data type error or automatically do the
converting, but that is another issue/bug.
I changed the line to
P_C_paint=: gllines_jgl2_ bind (10 <.@+ ,/"2 P-"1<./,/P)
then it work ok.
However, your line still crashed.
P_C_paint=: gllines_jgl2_@<.@(10 + ,/"2 P-"1<./,/P)
I suspected it couldn't coerce data to integer but I have no idea
what's wrong.

The xywh wd command and the rightmove and bottommove parameters are no
longer valid. Simply removing them from the wd command list is
sufficient to cause the crash.
Alternatively, an updated wd command list also causes the crash:
pc P closeok;
setp wh 250 300;
cc C isigraph;
set C sizepolicy expanding;
pas 0 0;
pshow;
The crash happens in the paint event handler (the qt window comes up
fine with P_C_paint=: ]).
Simplifying the represented data with N=:2 still produces the crash
P_C_paint=: gllines_jgl2_@<.@(10 + ,/"2 P-"1<./,/P)
still produces the crash.
