The following bug report has been submitted:
Platform: macOS-15.6.1-arm64-arm-64bit
ChimeraX Version: 1.11.dev202510142259 (2025-10-14 22:59:05 UTC)
Description
There is a bug in the scene restore code where it calls the
restore_scene() method for a Model multiple times. In this session
I have 5 models and submodels open and restore_scene() is called 5 times
on my one VolumeSurface instance which makes it very slow.
This appears to be an indentation error on line 196 of scene/scene.py
where the for loop
for model, scene_info in self.scene_models.items():
is inside another for loop that loops over all the models.
