Hello Bryan,
I am not surprised it works well on your side, examples work great for me as well.
Pinning it down more precisely, it occurs that the glitch is introduced in a CustomJS x-range callback:
when FixedTicker.ticks is set to a new array (this occurs when various zoom levels are reached).
(note that TickFormatter labels are set as well in the callback but are NOT at the origin of the glitch)
In 0.12.10, no latency, totally fluid.
From 0.12.11 on, latency is introduced.
I could check pre and dev releases to locate when exactly the latency was introduced, unless something obvious comes to your mind concerning ticks or related.
Thanks

Hi,
I use Bokeh daily and I have not experienced anything like you describe. In particular if I go to
https://bokeh.pydata.org/en/latest/docs/user_guide/layout.html
Then all the plots an the page zoom as I would expect, in Chrome, FF, or Safari on OSX. Same for random selections from the gallery. Additionally on Chrome specifically I can't reproduce any of the console messages you are seeing.
So, to investigate at all what is evidently a platform-specific issue, we would need much more information, such as full system and python environment and browser version information, as well as a complete minimal code sample to reproduce. In this case it would also help to have already-generated HTML files from different versions that exhibit the different behavior.
Thanks,
Bryan
