Hi All,
I have used the Xy-pic code:
$\begin{equation*} \xymatrix { X \ar[r]^{\Large {i}} \ar[dr]|{\large {f}} \ar[ddr]_{\Large {i}} & A \,\,\, \ar@{.>}[d]^{\large {\theta}} \ar@[red]@`{[]+/r3.5pc/, [dd]+/2.5pc/} [dd]^(0.35){\color{blue}{\large{Id_A}}}\\ & G \ar@{.>}[d]^{\large {\varphi}} \\ & A & } \end{equation*}$
to draw the diagram in my Moodle course .
It works with Moodle 3.7.* : 
,
but not with Moodle 3.8.*: 
How to fix it?
Thanks.
Best Regards,
Forlink
