Just installed SR11 due to a different error I had.
First thing I noticed is that when I select objects the yellow selection flashed between the standard visibility (Isocurves and 2px thick surface edges) and my custom visibility (no Isocurves and all 1px thickness). The flashing happens only when I rotate or pan the camera. It even stays in that state when I stop moving. See images:
Hmmm - what I see is that on selection, the display mode specific settings go out the window and I see the full wireframe highlighted.
I think this is how it is designed to work. I see from your previous SystemInfo report that your drivers are from March of this year - it might be worth going to the NVidia website and getting whatever their latest driver is for your card.
I agree, that’s how it should be. I installed the latest display driver but it didn’t help.
I don’t want to sound crazy but the flickering is only happening on SOME objects in my file. Specifically, those I have been working on since I updated yesterday. And, it’s also only happening if I zoomed in on the objects. Once I zoom out far enough the flickering stops.
I have copied those objects into a new file and it stopped flickering. Weird?
Correction. It doesn’t flicker any more but it does switch between those two selection “modes” once I zoom in enough so that the object is larger than the viewport - roughly.
doesn’t matter what file, the flickering persists. When I’m far away from the object the selection shows the full wirefram. When I zoom in it starts flickering.
Hmmm. But some objects and not others - is that still true? Is there any obvious difference, like object type (Meshes, surfaces, curves etc) that corresponds to the behavior?
Interesting additional observation: if i reduce the wire thickness with testwirethicknessscale to, for example, 0.5, the flickering is doing the same thing to all wires - flickering between 0.5 and 1.0 wire thickness.
Hi Oliver - thanks - this is something of a shot in the dark but just to eliminate a possibility, can you please disable VRay in Options > PlugIns page and then restart Rhino and see if that makes any difference?
I copied a few of the objects from this file into a new file and didn’t have the problem afterwards. Maybe the file is weird or too big (it’s not really big but full of blocks). Only when I copied more and more objects did it start flickering again. Not exactly sure if it’s related to one specific object in my file or the size, or a material.
Hi Oliver - thanks for the details - I’m beginning to suspect an object or objects - did you copy blocks into the new file? Can you try deleteing half of the objects and see if the problem goes away - if not Undo and delete the other half… if so, repeat by halves until you can isolate the object(s). Should be fairly fast… Or just send us the file (tech@mcneel.com) and see if we can reproduce it…
I’m afraid it happens in other files as well, even those I made before SR11. It didn’t matter which objects I deleted, as soon as there were more than a few I could see it happening.
