20432	ChimeraX bug report submission	iamkaant@…		"{{{
The following bug report has been submitted:
Platform:        macOS-26.5-arm64-arm-64bit
ChimeraX Version: 1.12rc202605280043 (2026-05-28 00:43:25 UTC)
Description
I've opened a session created by ChimeraX 1.11 and containing 4053 entries in a ViewDock window. The file size was ~14MB. After doing some hitpicking I saved the session and its size grew to 2.5 GB. I'm attaching a json file with some stats I was able to retreive from the session file
