[PD] [SOLVED!] GOP auto-moving issue with Pd Vanilla 0.53.1 under GNU/Linux and Windows

[Linux Rouen Normandie]

Hello João,

Thanks for your suggestions.
The first ones were not working, always the same jumping GOP issue.

So I spent some more time on analyzing the 1845 lines of my patch.pd 
file helped by this unofficial PdFileFormat article 
<https://puredata.info/docs/developer/PdFileFormat>.
After a lot of testing I found the culprit, it is #X restore... and any 
associated #X coords... lines.

In my case I was able to fix my issue by modifying the order of 3 lines.

* Original Pd patch file for Restore & Coords: BAD behavior
/#X coords 0 -1 1 1 853 280 1 995 265;//
//#X restore 10 7 pd smpsk;//
//#X coords 0 293.5 1 292.5 850 280 0;//
////
/ * Modified Pd patch file for RESTORE & COORDS: Now GOOD behavior
/#X coords 0 293.5 1 292.5 850 280 0;//
//#X coords 0 -1 1 1 853 280 1 995 265;//
//#X restore 10 7 pd smpsk;/

It seems to be a question of properly sorting this 3 lines, here manually.
But it should be the automatic task of the Pd engine to do it, isn't it!

I will open an Issue on Miller Puckette Git site.

Best, Joe
