Hi All,
Has anyone noticed the jumpy edges while dragging a marquee across the screen?
Cheers
Andy
This is probably related to your GPU. Please post your OpenGL settings so I can see what hardware you have.
I’ve been using Rhino for a good few years and never noticed it on the PC… It’s not been a problem with the other beta version of Mac Rhino until the last update the other day?
You think somethings flitted about since I updated, perhaps?

I have a Mac with a very similar GPU, but I cannot duplicate this. It looks like you are using ghosted mode. Can you post a copy of your model, and describe what display mode you are using? Have you modified the display mode?
Ah… I opened the file again to have a look and couldn’t recreate it but then I realised I had the items on the purple and yellow layers switched off.
It doesn’t happen in any other view than X-Ray, but here’s the clincher… The two layers that flash are transparencies - they’re glass in Toucan materials.
I think you should be able to recreate it now?
It really doesn’t bother me but thought I would raise it as that’s the whole reason for using the beta version, no? 
Nope, still cannot recreate the issue. I’ll need a copy of your model if you’d like me to look into this further.
