Yes, I think flatpak copies files somewhere else after the build and 
probably timestamps change. Here's an example:

[📦 org.frescobaldi.Frescobaldi test]$ ls --full-time 
/app/share/guile/2.2/ice-9/psyntax-pp.scm
-rw-r--r--. 2 nfsnobody nfsnobody 184880 2022-04-03 22:54:41.415067967 
+0200 /app/share/guile/2.2/ice-9/psyntax-pp.scm
[📦 org.frescobaldi.Frescobaldi test]$ ls --full-time 
/app/lib/guile/2.2/ccache/ice-9/psyntax-pp.go
-rw-r--r--. 2 nfsnobody nfsnobody 506061 2022-04-03 22:54:41.012067973 
+0200 /app/lib/guile/2.2/ccache/ice-9/psyntax-pp.go


Touching the .go files is not allowed by flatpak.
I tried this and got an error:

find /app/lib/guile/2.2/ -name *.go -exec touch '{}' \;
[...]
touch: cannot touch '/app/lib/guile/2.2/ccache/web/uri.go': Permission 
denied


I'll have to find a solution when building the flatpak.
Waiting for minutes or hours while CPU hits 100% is not an option.
