Session files get larger on each save

[drorn@…]

Hi,
I reported this bug before.
Sometimes, session file sizes get inflated for no obvious reason.
It happened to me again so this time I followed it more rigorously:
There is something in the session file that causes it to keep increasing the file size after each save. The only way to stop it is to quit chimeraX and reopen.
Here is a link to a folder with example session files. The original session contained 5 models with surfaces, I deleted the surfaces and saved as a different file, then I closed four models and save again in a different file, then closed the session and opened a single small structure from the PDB and save that one. In all those cases file sizes were hundreds of MBs. After restarting chimeraX it saved the small protein session as a small file. The names of the files in the linked folder are descriptive enough for you to follow. I\u2019d appreciate taking care of this bug.

Hi Dror,

As per the previous ticket (​https://www.rbvi.ucsf.edu/trac/ChimeraX/ticket/10007), the fixes went into the 1.7 daily build (which is now the 1.7 production release). Were you using the 1.7 release when getting this behavior? In the other ticket you submitted today you were using the 1.6.1 release.
In case you were using the 1.7 release, I have requested permission to access your Google Drive folder.
