Hi

I am currently using the ChimeraX Daily version - UCSF ChimeraX version: 1.2.dev202102050202 (2021-02-05).

I am working with the pdb: 6j5k - a slightly large protein. If I 'hide atoms' and only 'show cartoons', I can navigate the protein visualisation using my mouse quite well - rotations, translations, zooming etc.

However, once I generate the surface and then adjust the slider-side-view to adjust the views to visualise certain aspects of the protein, I have noticed that the computer becomes exceedingly slow to render even small rotations using the mouse - I can understand that this might be because the protein is big. 

However, the next part - if the surfaces were now deleted and only cartoons are shown in the same session (as in the beginning), the computer is exceedingly slow for mouse work - rotations, translations, slider-view etc.

Is there some way to refresh and regain back this agility and remove this hysteresis? The only workaround seems to be to close ChimeraX and then reopen it again, but this is not slightly more tedious if we have to close and reopen every time I make a surface.

The commands I have used are:

Then try to navigate...

And then navigating again....

If there could be some work-around, or a new fix in the ChimeraX_version, it would be really helpful for working with large proteins seamlessly.

Thanks
