As Mr. ChunEon said, this is a internal bug of the SGX driver and evas GL engine can't know whether the GL program is loaded properly or not.
In error case, there is no detectable error information about program binary loading thus the evas can't handle GL error state.

Codes don't know which device breaks the binary shader rutine. It means, Even it succeeded for binary shader functions, the rendering do not work fine since it's the driver internal problem. Actually, gl_module can't handle this exception commonly. ------------------------------------ Let's run together for the best moment! -Regards, Hermet- -----Original Message----- From: "Cedric BAIL"<cedric.b...@free.fr> To: gl77....@samsung.com Cc: enlightenment-devel@lists.sourceforge.net Sent: 11-07-13(수) 17:40:38 Subject: Re: [E-devel] [Patch] evas_gl_shader patch for get_program_binary extension2011/7/12 이광림 <gl77....@samsung.com>: > Dear all, > > I attached a patch of evas_gl_shader. > > I've removed a comment which is creating dummy shader when using > GL_OES_get_program_binary extension. > Mr. Haegeun Park who is in charge of GPU driver fixed get_program_binary bug > in the SGX driver. > There's no need to create dummy shaders any longer. > > And I've added link status checking code to validate the binary object. > > Please review this patch. Just wondering is this bug affecting all SGX driver or just specific to the version you are using ? If it's not a fix for all SGX driver, it would be usefull to provide a fallback mecanism and create a dummy shader when the get program binary fail (if that make sense). -- Cedric BAIL ------------------------------------------------------------------------------ AppSumo Presents a FREE Video for the SourceForge Community by Eric Ries, the creator of the Lean Startup Methodology on "Lean Startup Secrets Revealed."
