Text/Dimensions are Slow in Rhino 7

[JVN (Justin)]

When I click on text or dimensions, it takes 2-3 seconds for the properties window to update. Same thing when I unselect the text. During this time I can’t do anything else… slows down my efficiency immensely. I tried making a new file with nothing in it except one text, same thing. I still have Rhino 6 installed and it is instant.

Using a new Dell XPS 17 (2020)

Thanks in advance.

Hello - if I remember right, this has come up before and works fine if the Properties panel is not showing - is that the case for you?

-Pascal

[JVN (Justin)]

Yes, that is the case for me.

[JVN (Justin)]

Is there a solution that doesn’t include hiding the properties?

[pascal (Pascal Golay)]

Hi Justin - Please see if getting the current SR2 release helps - I believe this was fixed.

-Pascal

[JVN (Justin)]

Hi Pascal,

Unfortunately I’m fully updated and it hasn’t solved this problem. Any other ideas?

Thank you

[pascal (Pascal Golay)]

Hi Justin - I am not sure when that fix went in - I’d try this:
Open Options > Updates and Statistics page and set Update Frequecy to ‘Release Candidate’. Then click on ‘Check now’ - I am pretty sure that will get you a build with the fix - if not, then the fix needs to be refixed…

-Pascal

[JVN (Justin)]

Just did it, installed the new build and still have the problem.

[pascal (Pascal Golay)]

OK - let me see what I can find. As I recall, we did not see this problem, only some users did so it might be hard to track down.

-Pascal

[JVN (Justin)]

Weirdly I had the same issue in Rhino 6 on my old computer. I got a new computer and when I installed Rhino 6 I didn’t have the problem. Now I have it for Rhino 7.

[pascal (Pascal Golay)]

@JVN - just in case - can you try TestToggleSpellCheckOnAnnotationText and restart Rhino? Does that make any difference?

-Pascal

[JVN (Justin)]

Tried it. It was already off, but I tried it both ways to no avail.
Thanks

[jeffoulet]

Hi @JVN,

Just some dumb questions, as your problem might be related to what I’m currently experiencing:

• which font are you using?
• does the lag duration gets correlated with the text length (the more lines of text you have, the longer the lag lasts)?
• does your CPU shows anormal activity during the lag? Something like this:
  
  

EDIT: @pascal, you might to have a look at the following thread, as this issue still occurs on R7.3:

Rhino 6 SR22 and rhino 7 wip Lag bug

Hi, Any improvements on this topic? I tested to disable spell check as adviced here (Rhino 6, 6.30.20266.14531): "Text" is extremely slow and here: Bug - Automatic spell checker in Text properties freeze cpu …without any kind of success: text object selection still lags a lot. Moreover, on file start, the text panel is also not display properly: [20200928_text_lag] Is there any hope this issue will be fixed one day?

[pascal (Pascal Golay)]

Hello - @jeffoulet thanks, I’ll see if I can get someone with a bigger brain than mine to look at this.

Here, I do get a lightly larger bump in the cpu graph selecting text than something else, but it is all very small - nothing at all like what you show.

@jeffoulet , @JVN - does it make any difference what font is in the selected text?

-Pascal

[jeffoulet]

Hi @pascal, thanks for having a look at this.

What I’ve found out on my side so far:

TestToggleSpellCheckOnAnnotationText is disabled.

• regardless the font, the text panel always requires 0,5-1 seconds to be displayed, when an annotation is selected as nothing was selected before. This makes the user experience really frustrating:

  
  
  Switching between objects is more fluid and work as expected:
  

• by standard fonts (Arial, Times New Roman etc.), it seems to be no lag. By some other fonts families, the lag also does not seem to appear for the main font (let say Encode Sans), but is present for sub-types of that family (Encode Sans Light, Encode Sans Condensed…):

  

• finally, the lag length is related to the number of lines in the text object. More lines = heavier lag:

  

There is definitely some nasty loop somewhere…

Here is the file: text_lag.3dm (84.4 KB)

@jeffoulet - thank you - this is exactly what we need.
Jeff, the fonts that are slow are not installed, here - are they, on your machine?

RH-62653 Text selection lags

Thanks for your patience and perseverance, y’all.

-Pascal

[jeffoulet]

Yup, these fonts families are installed on my PC. See here for instance: Google Fonts
Each one comes with a bunch of ttf for each style:

[pascal (Pascal Golay)]

Hi Jeff - thanks - here, if I install the fonts the lag goes away completely, so far.
