Priority: medium
Bug ID: 66886
Assignee: [email protected]
Summary: eglChooseConfig returns true even if it fails matching
the config
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: [email protected]
Hardware: x86-64 (AMD64)
Status: NEW
Version: git
Component: EGL
Product: Mesa
eglconfig.c:727
i think this should return false
http://www.khronos.org/registry/egl/sdk/docs/man/xhtml/eglChooseConfig.html
i was trying to run this function with
const EGLint pi32ConfigAttribs[] =
{
EGL_LEVEL, 0,
EGL_SURFACE_TYPE, EGL_WINDOW_BIT,
EGL_RENDERABLE_TYPE, EGL_OPENGL_ES2_BIT,
EGL_NATIVE_RENDERABLE, EGL_FALSE,
EGL_DEPTH_SIZE, EGL_DONT_CARE,
EGL_NONE
};
and it would fail matching a config but the function would return true letting
me think that everything went fine.
https://bugs.freedesktop.org/show_bug.cgi?id=50870 <-- might be similar to this
i changed the data to this
EGLint pi32ConfigAttribs[5];
pi32ConfigAttribs[0] = EGL_SURFACE_TYPE;
pi32ConfigAttribs[1] = EGL_WINDOW_BIT;
pi32ConfigAttribs[2] = EGL_RENDERABLE_TYPE;
pi32ConfigAttribs[3] = EGL_OPENGL_ES2_BIT;
pi32ConfigAttribs[4] = EGL_NONE;
and it worked
