Rainbow glitch polygons on early 2008 MacBook Pro (NVIDIA GeForce 8600M GT 256 MB)

[0joshuaolson1]

My laptop is running 10.10 Yosemite with OpenGL 3. After correcting the target OS version in Milligram/mgSendLog/BuildOSX/mgSendLog.xcodeproj and building in Xcode 6.1, every demo and game runs, but each varies in how many rainbow squares are in the upper left corner (and in SeaOfMemes with a rectangle in the upper right). These block most of the view, and do not change size after window resizing. In GuiTestAll (but not TestCube for some reason) they disappear precisely while the player is moving forward or backward, and the whole screen is obscured. In SaucerMovie, the squares become more orange once the saucers start coming. In Trees, the color oscillates, with a more triangular pattern at times, sometimes stopping or switching between only two patterns. DontHitMe has no problems at all with the exception of a possible rainbow cursor square.

The small rainbow square appears wherever the pointer is in the window (unless the other squares disappear). In Landscape and Crafty, other rainbow polygons show up around the edge of the screen. One benefit of the fact that the big grid of squares often disappears during screenshots is that we get a better view of those aberrations.

Do you ever see the correct textures? (not gray).

I'll try upgrading my machine to 10.10 and see if it fails. Meanwhile,
look in the errors.txt log that the programs write and see if you are
actually getting OpenGL 3.2, not 2.1. I'm not sure the old 2.1 support
still works.

That all looks fine. I'll try it here on my MacBook Air under 10.10 and
see what it does.

I installed OSX 10.10 and the latest XCode, and it all works on my
machine, with Intel 4000 graphics.

The large "rainbow" rectangles are the GUI overlay textures, which are
256 by 256. But you don't seem to be getting any textures on your
graphics. Something in OpenGL is just not implemented correctly for
your machine.

The only things I can suggest are

1. find some other OpenGL application and see if it runs. Perhaps some
   short "texture a triangle" lesson from one of the OpenGL tutorial sites?

2. in XCode, there were some warnings wanting to reset the project
   defaults to accommodate the current machine and OS. Look for a yellow
   error triangle on the library projects like Milligram/mgPlatform or
   Milligram/mg3D. You could try clicking on that and letting it modify
   the projects. It made no difference for me, but perhaps it will for you.

3. Each of the demos/games has a file "options.xml". Try
   TestCube/options.xml. Edit that with a text editor, change the line
   'platform=""' to platform="OpenGL2.1". This will try to use the older
   version of OpenGL. I have no test machine for this platform, so it may
   just crash trying to render the GUI (which uses some newer GL calls.)
   If it does crash, go into TestCube/Source/MovementApp.cpp Find the
   method "setUI". Change "m_ui = ui" to "m_ui = NULL". See if that runs.

Let me know what you find out. I'm sorry, but there's no way I can
debug this remotely.

Michael.

[0joshuaolson1]

I'm glad it works on yours. Like I said before, I don't really have a use for this stuff, but I'm glad I could help a little.

[mgoodfel]

I find this stuff almost impossible to get working for everyone. There
are just too many variations between machines. If you can try the
things I suggested, I'd appreciate it. Thanks for testing the code.

Michael.
