According to IRC, "eglext-tests" package provides tests. At least the following extensions are missing according to the tests and claimed to be used somewhere in Mer or Nemo:
- EGL_NOK_image_shared
- EGL_NOK_swap_region2
- EGL_KHR_lock_surface2
Qt5 doesn't seem to contain any EGL_NOK usage but Qt 4.8 does:
xxxx@yyyy:/tmp/qt-everywhere-opensource-src-4.8.4$ grep -nrI EGL_NOK_ .
./src/opengl/qgl_egl.cpp:258: if (!QEgl::hasExtension("EGL_NOK_image_shared")) {
./src/opengl/qwindowsurface_gl.cpp:449: haveNOKSwapRegion = QEgl::hasExtension("EGL_NOK_swap_region2");
./src/opengl/qwindowsurface_gl.cpp:453: qDebug() << "Found EGL_NOK_swap_region2 extension. Using partial updates.";
./src/plugins/graphicssystems/meego/qmeegoextensions.cpp:89: qFatal("EGL_NOK_image_shared not found but trying to use capability!");

./src/plugins/graphicssystems/meego/qmeegoextensions.cpp:173: if (QEgl::hasExtension("EGL_NOK_image_shared")) {
./src/plugins/graphicssystems/meego/qmeegoextensions.cpp:174: qDebug("MeegoGraphics: found EGL_NOK_image_shared");
./src/plugins/graphicssystems/meego/qmeegoextensions.cpp:185: if (QEgl::hasExtension("EGL_NOK_surface_scaling")) {
./src/plugins/graphicssystems/meego/qmeegoextensions.cpp:186: qDebug("MeegoGraphics: found EGL_NOK_surface_scaling");
./src/gui/egl/qegl.cpp:617: if (QEgl::hasExtension("EGL_NOK_swap_region2")) {
./src/gui/egl/qegl.cpp:660: qWarning("QEgl::eglSwapBuffersRegion2NOK() called but EGL_NOK_swap_region2 extension not present");
NOTE: It seems that all NOK extensions might be used mostly for performance and only if available. So not having them doesn't seem to be fatal at a quick look.
See EGL_extensions for a list of extensions and how they are supported on different hardware.
