screenshot of wrong rendering at start

The water in the river in the middle and start of the map renders complete
black, not blueish with reflections like it should.

Will post glxinfo if requested. Attaching screenshots.

What chip and version of mesa are you using?  Is this a regression?  If so, can
you bisect?  Please attach your xorg log, dmesg output, and glxinfo output. 
Also if this game is a 32 bit game running on a 64 bit distro, please make sure
you are using an updated version of the 32-bit 3D driver.

AMD RV770 (AMD Radeon 4870), git 20130411 mesa, I will check with this is a
regression, will bisect if possible. Attached above. This is 64bit game running
on 64bit system.

I suspect it's not a driver's bug, there is a bug in the game itself. I can't
login and start a game right now (looks like I need to download a special
version of game client for my country), but there is an example of water
rendering in the video settings screen that is accessible without login, and it
becomes broken for me with evergreen card after changing and applying some
options, e.g. resolution in non-fullscreen mode, that is, after engine
reinitialization. 

I've looked into it and it seems the game tries to use a texture for the
framebuffer attachment right after deleting it. Looks like it generates new
texture object, but continues to use old name. Possibly with other drivers
(non-mesa) the name returned by glGenTextures is usually the same as was
deleted by glDeleteTextures right before that, and this might explain why the
bug wasn't noticed.

If your issue is the same, then you should see the following error in the
console when you run the game with MESA_DEBUG=1:

Mesa: User error: GL_INVALID_OPERATION in glFramebufferTexture2DEXT(non
existant texture)

Also you might want to use apitrace to create the trace that reproduces this
issue, and you should also see the errors like this when replaying it:

1239444: glDebugOutputCallback: High severity API error 1, GL_INVALID_OPERATION
in glFramebufferTexture2DEXT(non existant texture)
0 1239444 glFramebufferTexture2DEXT(target = GL_FRAMEBUFFER, attachment =
GL_COLOR_ATTACHMENT0, textarget = GL_TEXTURE_2D, texture = 67, level = 0)
1239444: warning: glGetError(glFramebufferTexture2DEXT) = GL_INVALID_OPERATION

If you believe your issue is different, please upload the trace file somewhere
so that it will be easier to reproduce the bug.

Closing... Not a bug in Mesa, it is a bug in the game renderer.

Can you (or someone):

1. Run the game in gdb.

2. Set a break point in _mesa_problem.

3. When the break point is hit, go 'up' a level and 'print target'.

4. 'bt full'

5. Report the results back here.

I'm curious what's going on.

I managed to start the game and it seems there are different problems with
water rendering, and I don't see framebuffer-related errors in the game.
Possibly I was wrong, I'll look into it to see if it's something related to
mesa or the driver.

Btw, Ian, here is a backtrace for BindTexture error (target is 0).
Breakpoint on _mesa_problem didn't catch it, so I used _mesa_error:

Right, I always get those backwards.  Sorry. :(

That's definitely no good.  0 isn't a valid target, and 2079 (0x081F) isn't
either.  Weird.

I tested it with catalyst 13.1, there is the same rendering issue (water is
black with some video settings), and similar BindTexture calls with target 0,
so I think it's not a mesa/r600g's issues.
