Strange behaviour in Ubuntu 22

Hi GTK Team!

I have develop a simple application using GTK+3. This application has been compiled in Ubuntu 20 (GTK 3.24.20) and runs ok in this system. If I move the binary to Ubuntu 22 and runs, the main window dimensions are wrong...

But, if I run the same binary in Ubuntu 22 from VSCode terminal, the application works fine again.

Same binary

Run in Ubuntu 20 --> OK
Run in Ubuntu 22 --> Wrong
Run in Ubuntu 22 VSCode Terminal --> OK

More info about this problem on this thread: https://github.com/frang75/nappgui_src/issues/12

Any suggestions as to what might be going on would be helpful. Thank you soo much!
