<div><br></div><div>I'm currently experiencing these kind of errors when i'm running various OpenGL apps(a little more complex than glxgears ;-)</div><div>These kind of errors are easily trigerred by software like Dota 2 or XFLOW <a href="http://xflowcfd.com/">http://xflowcfd.com/</a> or other CAD packages under Linux(Siemens NX ,etc)</div>
<div><br></div><div><br></div><div>I have Asus K73S Series laptop running Ubuntu Raring.</div><div><br></div><div>What is the problem with i915 driver , displaying these problems for so many years?</div><div>Running a decent(professional) OpenGL on such a hardware is in fact impossible( and it's not because it lacks the required OpeGL functions).</div>
<div><br></div><div><div> I can provide acces to XFLOW software if it has any use in debugging these problems.</div><div>Otherwise let me know what i can help with.</div></div><div><br></div><div>Regards</div><div>Victor Mierla</div>
