gl_tests:DrawArraysThenDrawElements: glFinish instead of swap Later in the test we read from the backbuffer to confirm that the triangles were drawn correctly, but without EGL_BUFFER_PRESERVED the content of the backbuffer is undefined. Since glReadBuffer is not supported in GLES2 don't swap, instead to a glFinish to force the drawing in each iteration.
