Yeah was just talking with Kristian about this. According to the SGI_swap_interval spec, the default value should be 1. For direct rendered clients we should probably just make them send a swap interval protocol request so that the server will match up and all will be in sync. That way we won't have to keep the server and mesa in sync by hand. I'll get to it later today unless Kristian already has a fix. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
