I’m using blender 2.61 on Mac OsX Snow Leopard.
Every once in a while while navigating 3d space (e.g panning around a model) blender locks up for a second or two then snaps back and has finished what I asked it to do.
My system reports a massive lag spike in my computers CPU after this happens.
The Mac console is empty.
For the record, you’re not the only one experiencing this problem; the same happens here on my MacBook Pro running OS X 10.6.8. I’m not using any textures at all and the models I’m working on at the moment are pretty light. On the same laptop Blender runs fine under XP.
Since having upgraded to OS X 10.7, this issue has disappeared on my system. It’s disconcerting though that you’re still experiencing the problem even with the 2.63 release; if it hasn’t been reported before it is probably a good idea to add the issue to the bug tracker.
There is something going on, internally, with the GUI. I think it is excessive redraw events. It has not been right for a while. With the release of bMesh the Blender interface just seems slower.
Same problem here. Also since a few versions, although I thought it dates back to even before 2.61 (might be wrong though).
I’m also working on OS X 10.6.8. I can tell very clearly that the entire system is frozen because the second counter in my menu bar clock stops for a moment.
I think the problem can be avoided by working in wireframe mode, but of course it’s not very feasible to always work in wireframe mode.
