Hello Colleagues :) ,
I am working on a major project lately, but the last thing I was experiencing was heavy synchronization issues with g_thred_new.
-
After a while I found out that the problem is because I modify/update application's GUI from the thread.
-
By problems I allude generally application text damages such as showing non-standard characters instead of the widget's intended text, sometimes
even crashes and asserts.

Is that correct  and I should not make changes to the GUI inside such thread ?

You *cannot* use GDK or GTK+ API from any other thread except the one that called `gtk_init()` and `gtk_main()`, or `g_application_run()`.

https://developer.gnome.org/gdk3/stable/gdk3-Threads.html

Is there any way I can do that within the thread without ending in a symbolic mess ?

No, there isn't.

The common pattern is to schedule UI changes from separate threads using API like GTask.

Ciao,
 Emmanuele.
