Bug ID: 98310
Summary: GLES context returned by OpenGL API
Product: Mesa
Version: git
Hardware: Other
OS: All
Status: NEW
Severity: major
Priority: medium
Component: EGL
Assignee: [email protected]
Reporter: [email protected]
QA Contact: [email protected]
The ultimate consequence of this bug is that EPoxy thinks that the current
context is OpenGL, although it is GLES2. It reports this up to GTK/GDK which
then abandones GLES2 rendering (because it thinks OpenGL is being used).
EPoxy tests whether the current context is OpenGL by
epoxy_egl_get_current_gl_context_api( )
in two steps, by first binding the API which is being tested for:
eglBindAPI( EGL_OPENGL_API );
and subsequently testing for a context
if( eglGetCurrentContext( ) ) ...
I don't know whether this is actually a proper way of testing this (or why this
is required by further up in the first place), but I can definitely say I do
NOT have OpenGL (simply because of the lack of X11 libraries and I built Mesa
only with GLES2) but that call, after the OPENGL_API was bound, returns a
context. Which in turn makes Epoxy think that the context is OpenGL.
