I see it too. I am running OSX 10.11.2 the latest with Chrome 47, the
latest.

Internet Explorer was unusably slow with JSmol.

Recently I began to notice jumpier rotation in Chrome, while Firefox and
Safari continue to perform well.

Today I found Chrome to be unable to rotate any molecule (even caffeine) in
JSmol. Although there are brief moments when rotation can be seen, these
are broken by long freezes (> 5 sec) when no rotation can be accomplished.

The problem is worst when the mouse is moved quickly. The molecule freezes
until the mouse is stopped. If you keep moving the mouse, the molecule may
freeze for more than 10 sec. The molecule does rotate with very slow
movements of the mouse.

The problem occurs in OS X, where Chrome has updated to version 47.

Rotation is still quite good in Chrome version 46, which happens to remain
in my Windows 7 and 10 machines, despite version 47 becoming the stable
release on December 1 (

Presumably my Windows Chrome will shortly auto-update to 47 and then I will
be very curious about performance.

I tested the OS X beta version of Chrome, version 48, in hopes the problem
would be fixed -- but it remains in Chrome 48 in OS X.

Since Chrome stopped supporting Java on September 1, 2015, Chrome is now
useless for JSmol websites.

We can hope this is a mouse-related bug in Chrome that will be fixed, but
as I mentioned, a fix is not present in the current beta version 48.

This is a sad turn of events! Comments? Suggestions? Insights?

Dear Eric,
I’ve noticed the same problems, especially on older computers where each scene 
repaint can be perceived (white background flashing between each frame). One of 
my pages has other concerns related to javascript event listeners that make the 
whole experience even worse, by adding other calculations to the webpage on top 
of JSmol. My students noticed that firefox is better too.
I have a simpler webpage with only buttons for interactions that doesn’t have 
the same drawbacks (animations are quirky, but user interactions are 
satisfactory).

As this situation has been quite frustrating, I’ve decided to give WebGL a try 
using 3dmol.js. I am in the process of rewriting a single page application 
around a viewer, but it’s like reinventing the wheel as this library 
capabilities are far from being on par with JSmol and rely on a totally 
different mechanism of interaction (David Koes, its main developper, is very 
helpful in this process). Most Jsmol features lack form this library which 
focuses on rendering. I’ll see if it nonetheless could suit my teaching needs 
in biochemistry…

[Jmol-users] Fwd: Chrome: rotation unusable in JSmol

2015-12-10 Thread Eric Martz 
In April 2014, Chrome gave the best performance of JSmol: smoothest 
rotation and few if any long (~ one minute) pauses during loading of 
some modest PDB files (pauses seen in Firefox). I configured FirstGlance 
in Jmol, when using JSmol, to recommend Chrome over Firefox. Safari was
