Are these messages serious, any things i can provide to get rid of them?
They mean that some rendering operations are dropped, do you notice any visual elements missing or looking incorrect? Is there anything related in the stderr output of 3D apps?
Please attach (as opposed to paste) the output of glxinfo.
