Thanks Michel..
sorry if my description is not clear.
Yes I have used with glxgears in fullscreen mode and also a simple glxapp which actually opens in fullscreen by default.
In both the cases, the issue is same.
Just wanted to know if AMD has done anything different apart from the configurations either in MESA or in its Radeon driver ?
Thanks

not for the window which is fullscreen and using page flipping (your
description is a bit vague to be sure though).
Have you tried with a simpler test app, e.g.
glxgears -fullscreen
?
