--- Comment #4 from Simon Farnsworth 2011-06-30 08:09:03 PDT ---
Added more logging - I'm clearly wrong, because I see that I enter the
following codepath around line 1100 of radeon_dri2.c in
radeon_dri2_schedule_swap, which converts DRI2_SWAPs to DRI2_FLIPs.
/* Flips need to be submitted one frame before */
if (info->allowPageFlip &&
DRI2CanFlip(draw) &&
can_exchange(scrn, front, back)) {
swap_type = DRI2_FLIP;
flip = 1;
}
