Rhino freezes terribly while generating an extensive User Text lists

Rhino freezes terribly while generating an extensive User Text lists

This makes working with imported IFC models, which can be heavily saturated with User Text, very unpleasant. At the beginning of the recording I shake the camera when User Text is not displayed in the Properties Panel and it works quite smoothly. However, when I switch to the Sub-Panel Attribute User Text, the more elements are selected the longer I have to wait for the User Text to be generated and only then can I move the camera again. The recording shows how long it takes Rhino to unlock camera movement, and this is a very simple building… about a few seconds, strangely enough, in two rounds.

I don’t know how it looks from the technical side, but of course it would be best if the camera movement in the Viewport was not blocked by anything that happens in the Panels, so asynchronously. If not, I really hope that this process will be accelerated many times over.

I deliberately narrowed the Panel so as not to display any data unnecessarily.

Firstly I show regular behavior, later part of the video shows freezes

I’m attaching simple script to generate geometry with User Text to quickly test the performance drops.
I see that my post was seen by only 19 people, I doubt it reached the devs…

Even selecting 100 objects results in noticeable freezes.

I’m wiggling the cursor that should orbit the camera so you can see the viewport freeze time better. Previously I used Rhino 8, this time it’s in Rhino 9 WIP.

@Gijs Can you please tell me who might be interested in this issue?

User Text Lag.gh (13.8 KB)

It looks like we have an issue on the UI.
It’s fixed on the next RC.
