[Paraview-developers] color scale editor issues on mac (Error: GL_INVALID_FRAMEBUFFER_OPERATION)

[burlen]

Hi All,

on Mac OSX 10.8.2 with a recent pull from master I'm encountering OpenGL 
errors from the pqColorScale editor dialog. I don't have much experience 
with the Mac so I'm hoping someone out there can take a look?

To reproduce: start paraview (and attach to ParaView using Apple's 
OpenGL Profiler with "break on open gl errors" set), create a wavelet 
source, slice, color by RTData, open the color scale editor. At this 
point in the terminal:

    2013-03-16 14:39:04.866 paraview[28716:707] invalid drawable
    2013-03-16 14:39:04.867 paraview[28716:707] invalid drawable

The profiler shows the following back trace:

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)

It's causing me problems because it's reported when I check for gl 
errors in my code. I'd really like to leave the error checking enabled. 
I filed a bug report : http://paraview.org/Bug/view.php?id=13947

Thanks
