System Information
MacPro (early 2008)
OS X Version: 10.10.5
Graphics: NVIDIA GeForce8800 GT 512MB

Blender Version
Broken: Blender 2.76(48f7dd6). Note: Recall same problem while testing version 2.75
Worked: Blender 2.74(000dfc0)

Short description of error
Unable to use blender editor windows.
Attempt to interact with blender buttons( example: Menu - Add - mesh) results in disappearance of all editor windows.
Flickering of User Preferences bottom bar.

Exact steps for others to reproduce the error
I simply try to add mesh or edit object but all the editor windows disappear (timeline,tools,properties etc) and even after I restore them via hotkeys or new project the problem will repeat.
I am aware of the possibility of graphic card issues, but my drivers are fully up to date and have never had problems. I also have tried every window draw method (Full,Overlap Flip,Overlap,TripleBuffer and Automatic), but to no avail.

Therefore I assume this is a bug with Blender 2.76
Any help appreciated.

Did you try a latest buildbot build version ?

Could you show a screenshot of the error?
Also please double check if this works in 2.75 or not.

This sounds similar to #46603, an error reported on MS-Windows (also reports regression with submenus in 2.76, working in 2.74)

Thank you for your responses.
Yes i have two screen shots here: and
I have noticed sometimes windows even flicker between each other.
The problem does indeed sound similar to #46603 with MS-Windows.
I am currently testing the latest buildbot version as suggested by Perfection Cat.

UPDATE:
I am afraid the problem persists with the latest Blender build version "c3cec82".
And I have double checked with Blender 2.75 (Gooseberry Branch) and can confirm the same problem.

Does this happen with all window draw methods?
Does using software opengl have any difference?

Hi Sergey,

Sorry I've been unable to reply until now.

Yes, it happens for all window draw methods. I have not used software openGL (as I do not know of a way to implement such a thing on OS X).

@MikeErwin, can you reproduce any of the issues?

No, how bizarre! From what I understand, one area is taking up the whole window. Flickering suggests other areas might be drawing but are covered by the last one drawn. Bug in glViewport or glScissor function that's 8800 specific?

My only Mac with PCIe slots is a quad G5 so no way to test locally. And my Mac nvidia cards jump from Geforce 6800 Ultra (older) to 650M (newer).

@AM-2 One way to run software GL is to reboot and hold Shift during startup. This disables hardware drivers.

system info:

OpenGL
============================================
renderer:	'Apple Software Renderer'
vendor:		'Apple Inc.'
version:	'2.1 APPLE-12.1.0'

Got this by holding down Shift on startup. Blender runs, looks a little weird but does not show the problem reported here.

Archiving since this is different code in 2.8, and we no longer officially support this macOS version and GPU.
