Cannot reproduce, MacPro 5.1, AMD 7970

Perhaps NV/Apple drivers ?


The lag also depends on size of the image in the editor, anything over 512 is hard to work with (I set 4k generated in the submitted .blend). If nobody complained about this before in bug reports, it's probably hardware/platform specific. I remember having same problem with previous versions of Blender on this computer.

Brecht Van Lommel (brecht) claimed this task.

I can reproduce the issue with Blender 2.74, exact same Macbook model but with OS X 10.10.3.

However with the latest build from this no longer happens for me, so it seems to have been fixed already.

Great. Thank you, works for me too.
