I did have a look at the source but couldn't understand really why
_EGLContext *share = _eglLookupContext(share_list, disp);
returns a NULL value for share. Had a look a bit more deeper and I saw
that the display values for both the contexts were different. I then
modified my code then not to open a new display for the new context
instead share the display with the older one and then everything
worked like a charm.
Thanks for your help. First step is usually the hardest step, so thank
for pointing in the right direction.
Another thing that I wanted to check was that I have ported some of
the performance demos from mesa demos to use EGL and GLES2.0. If it is
useful in general to community then how can I get the sources reviewed
and commit to mesa demos repository?
Thanks for your help,
Regards,
Divick
