GH2 stuck loading

Yes, exactly the same. If you load the plugins beforehand, opening the canvas takes about 5 seconds. Then everything is slooow. if you hover over a component button it takes 2 seconds to highlight. Then you click and and release on the canvas and again another two or three seconds during which you can actually see it fading into existence… a very spiritual moment.

Now that is interesting. I’m not doing any blending animations when dropping objects on the canvas. Possible clue there @curtisw?


Hi. Does your rhino 7 take a long time to load too?
Mine takes a few minutes because it takes a long time to load the Rhino Legacy Render plugin.

No, Rhino 7 loads at normal speeds for me, it’s just GH2 I’m having problems with.

Hi. I had some issues with windows so I reinstalled it, keeping the files so not everything is fresh. I had to reinstall rhino 7 and 8. The problem in rhino 7, loading the rhino legacy render plugin is gone. The problem in rhino 8 / G2 is still the same. I will try a clean reinstall soon. Any news on mcneel side?

@Frane See if this post helps: PSA - Repair, don't Reinstall

Hi @Gijs. Thanks but I finally ended up formatting the partition and reinstalling windows. It now works perfectly. At least it’s not hardware. Rhino was the first program to be installed so I should be able to see if and when it is affected by other software. Maybe @Brayton_Orchard can try to repair if it works.

@Frane, just clarifying: so after doing what you mentioned above, GH2 now loads quickly and is no longer laggy?

Yes, loads and works as advertised (fast).

@Brayton_Orchard, @DavidRutten @Gijs . here GH2 gets stuck at 7% if the display is set to 150% scale! (windows settings, display) At 100, 125, 175 and 200% it works fine!
@Brayton_Orchard does this solve your problem too?

Nice find @Frane!

Mine also works at 125% and 200% display scale, but not 150% (my default setting) or 175% (didn’t try 100%). Loading speed and canvas navigation seem very fast.

I cannot repeat that here unfortunately. I set windows scaling to 150%, restarted Rhino and G2, loads up just normal.

Hi Frane -

Thanks for that! We got this reproduced on a developer’s machine and put it on the list:
RH-72064 Grasshopper 2: Doesn’t load past 7% when display is scaled and Rhino is in dark mode

Hi Wim. Great that it failed on your side too! Just to be clear, in my case dark mode has nothing to do with it.
