this bug seems rather old, but for what I can say it’s not yet fixed. So I’ll go ahead and put some more details in.
I’m attaching a few more screenshots than I normally would do, because as you can see, the fragmentations vary from pic to pic. They all come from one model with no changes made once the first font problem became visible. All variations from then on came from zoom level modification and, very reproducible, from other application’s background activity in terms of memory consumption. The ‘best’ results I got happened after switching back to rhino coming from an app like a browser with opening large images in several tabs.
Please see my system’s configuration below.
Furthermore, this also might help:
This font rendering problem also happend in one earlier modell I was working on a few weeks back. Unfortunately, I didn’t do any screenshots then. The kind of fragmentation was the same like today.
This happend after a while (a few hours) of working on that model.
The font in question is Arial and is okay from what Font Book’s test routine tells. There are two or three problematcic fonts installed in user land, but they aren’t used by rhino. Also, these fonts appear to work fine in other apps.
If I close and reopen rhino and that model, the problems are gone.
When selecting one corrupt dimension using Gumball (4. pic) and move that one around, the sort and size of that corruption remains. Only resizing (zoom) that viewport and/or camera movement result in variations.
