I think if you are at least using the latest 1.12 release of Cogl you should have the latest fixes for cogl gles2 context issues we've seen. If you haven't already built Cogl with --enable-debug that might help to since it will enable Cogl to catch GL errors at source. kind regards, - Robert On Thu, Jan 31, 2013 at 1:59 PM, mahesh gawali <<a href="mailto:maheshgawali@gmail.com">maheshgawali@gmail.com</a>> wrote: > Thanks for the quick response Robert, Neil and Tomeu. > > I also have an ARM target to which i have ported webkit-clutter.
