You could try increasing the latency constant in that file to see if it makes the flicker go away. If that helps it's just another example of why we need better latency detection in the driver; unfortunately we don't know how to do that yet... -- Jesse Barnes, Intel Open Source Technology Center _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
