This does not seem to be what I asked for, unless you took the file, split it into two pieces and renamed them.
The file which I asked to send was /Users/christianvanelle/.ganttproject.d/logs/.ganttproject-20220615174650.log
Mille excuses, il y avait un fichier caché à droite : le voici, en espérant que ce soit le bon.
Bien à vous

ganttproject.log (2.25 KB)
This is not the log which I asked for. This log file was produced by the standard GanttProject.app from DMG package. It uses its bundled Java Runtime.
The name of the log file which is produced when you run ganttproject.command is printed at the end of your screenshot, and I copied it as text for you. Please run in your Terminal
cp /Users/christianvanelle/.ganttproject.d/logs/.ganttproject-20220615174650.log ~/Documents/TheLog.txt
and it will copy the log file into TheLog.txt file in your Documents.
Here is the result, is this the right file
TheLog.txt (2.78 KB)
Thanks! I see that it really uses the “native” Java Runtime. So, you say that if you run ganttproject.command, it is still lagging when you scroll the chart with a task?
Hi!
I have this problem too. I’m ready to help debugging.
Hello,
thanks for the will to help. Are you a software engineer? I mean, are you able to run development tools, like IntelliJ IDEA?
No, I’m a curious architect in love with GP
We remain confident, you have found the solution to absorb 4K, it is not 5K that will resist you!
The question was addressed to @Timofei_Korostelev 
So, here is GanttProject 3.3 Beta packaged for Apple Silicon computers using the latest long-term support Java 17.0.5:
https://drive.google.com/drive/folders/1C2IewskPtYExcjZcm2FTbOWxX2j_1ELi?usp=share_link
I kindly ask everyone in this thread who is having issues on M1 to download and try this package.
Hello Dmitry,
Congratulations and THANK YOU for this MAC M1 Apple Silicon update. CP is now running smoothly on my Macbook pro
Like any beta, there are still some hidden settings to find.

Good evening Dmitry,
The new “print” function is a nice evolution that will be very practical.
Currently on Mac M1, the print format sent by GP is not recognized by the printers. We ask for an A3 output, we get an A4
The ZIP format of the exported files is not recognised at all, so it is impossible to open them. Why ZIP and not PDF?
I’m still looking into it
Kind regards

nit: Printing was changed in 3.2. it is not new in 3.3
Will we soon have the solution on Macbook M1 as a result?
Pardon? What do you mean?
I mean you must have been facing since version 3.2 problems with printing and exporting files with Mac M1s and probably you are about to find the solution
Kind regards
Sincerely

This is the first time when such issue (page format different from the chosen) is reported. I don’t think it is related to M1. Anyway, printing is too fragile thing and I am not going to pay too much attention to corner cases. Gantt chart can be exported to either a single image or to a collection of images and printed using your favorite printing tools which are known to work on your platform.
You’re right, we can always go through “export” and output GP in the desired format
“Print” was just a bit more practical … we will survive anyway
More seriously: in a schedule there are critical tasks and others that are not critical and therefore have a MARGIN that the software calculates
In real life, this information is very important
Would it be possible to have this information in “Gantt chart properties”, “details” as well as the duration, the name of the task …
Kind regards
Please consider using other topics for discussing questions not related to M1 issues. In particular, this one is addressed in this bug tracker issue: A column indicating task float · Issue #1906 · bardsoftware/ganttproject · GitHub
