Merge pull request #334 from mathieu/ValidateProgramTooEarlyUnder macOS the glValidateProgram reports too many errors
Tue, 29 Aug 2017 11:34:27 +0200
Author : Mathieu MARACHE
Under macOS the glValidateProgram reports too many false negatives (errors) about missing buffers, etc..From the internet https://stackoverflow.com/questions/15335510/opengl-glvalidateprogram-error-on-mac-os-x :
« […] The purpose of glValidateProgram is not to use it as an added "check" step after linking the program, because the GL and application state is hardly ready for actually using that program at this point, probably it's even before we get around to initializing the default framebuffer (its bitdepth, its multisample buffers, etc), and that's what the error hints at.
An appropriate place to call glValidateProgram would be right before you make a real render call. »
