OS X - Grid Rendering Glitch

Development Programming & Scripting
1

Under OS X, I’m getting really varied results with grid rendering. This is one such example:

I’m on OS X 10.9.2, and a late 2012 27" iMac with a GeForce GTX 680MX.

Hey Geenz,

Is this happening 100% of time? If not, does it always look like this when it does happen? You mentioned experience is varied, and I’d like to know in what ways if you don’t mind. If there are any consistent repro steps, that would be great to have as well.

Can you tell us your machine specs (processor, memory)? Thanks!

Here’s another example:

Honestly, I’ve been looking more into how to reproduce getting grid rendering working correctly than how to reproduce this issue. I’ll start up editor, and either see no grid at all, a weird sheet of grey where grid should be, a malformed version of grid, or this red sheet where grid should be. Very rarely does grid ever function as expected.

My hardware specs are:
3.4Ghz Core i7
32GB of 1600Mhz DDR3

I’ve also attached my system report.link text

Here’s a few more:

Each of theses runs happened one after another. Checking under Windows to verify if this problem is unique to OS X or not, I don’t experience this problem

Thanks for this! We’re taking a look into issue and will update you when we know something.

Hi Geenz, I know you listed your OS X version as 10.9.2. But this looks awfully similar to a bug we’ve encountered with OS X 10.9.3 beta. Just a shot in dark - but can you double check your version?

As per “About This Mac”: OS X 10.9.2 (13C64)

As a workaround you can go back to an older version of editior grid by typing this into console (e.g. output log):
r.Editor.NewLevelGrid 0

or you add this to consolevariables.ini:
r.Editor.NewLevelGrid = 0

I think this should be helpful to you guys.
Taking Martin’s suggestion below as a work around to do a “before and after” sort of comparison regarding OS X performance issues, I found that by disabling and re-enabling new level grid actually fixes problem entirely.
