a few weeks back someone started a thread named Dimensions not showing to address display problems with dimensions, which I also had that time. So I’ve put in some of my observations and screenshots.
Now, with 5A701, the problem is still there.
And it is not limited to dimensions, but text objects in general. Today I can provide a few more hints that may help tackling that bug down.
The unwanted effects like the one in the picture above (and the ones in the abovementioned thread) are independent of model or document size. In fact the example here is a new model with one single text object. I had this issue with all of my models, sooner or later.
They are somehow related to system hibernation. The distorted text “test” occured right after one sleep-wake-cycle with Rhino running. The model hasn’t been saved to disk. The sleep-wake-relationship is a strong one, but it’s not a requirement for what I can say. I’ve also had distortions on a freshly booted Mac, especially with the next one.
A strong ‘supporter’ is OS X’s Spaces. I use Spaces a lot, and while switching between applications and their virtual screens, the pattern of the distortions vary. Sometimes between every single swipe from rhino and to rhino having it on it’s own fullscreen space. And they can start happening with the use of Spaces. One back-and-forth between Spaces and correctly displayed fonts are broken. Once they are messed up, they stay messed up until reload.
There have been cases when the distortion patterns changed live when zooming in or out. Or when altering the viewpoint on the model in Rhino’s Perspective Viewport.
They are gone (for a while) when I save the document and re-open Rhino and re-load the model.
The fonts I tested this issue with include Arial and Helvetica Neue. All fonts on my system are okay from what Font Book’s validation routine tells. My OS X is 10.10.1. If you need further details, pls let me know.
