[trungleduc]

Description

We are using jupyter-collaboration in jupytercad, in 2.0.5, reloading the page with an opened document causes a very long loading time. Below is the comparison between 2.0.4 and 2.0.5

• 2.0.4

• 2.0.5

2.0.5.mp4

The same issue happens with the notebook files.

If we cannot release just yet (#265), should we yank 2.0.5?

[krassowski]

I guess in other words, is this bug more severe than the issue addressed by #255?

[davidbrochart]

Hard to say, the bug addressed by #255 is more severe but less frequent, and the long loading time probably more frequent but just annoying.
