For the sake of testing, have you tried disabling page flipping in addition to SwapBuffersWait? (In reply to comment #12) > Down to dri2_drawable_get_buffers() now.

Yep, it's waiting for DRI2 buffer information from the X server, which is delayed until the previous buffer swap actually finishes. FWIW, you might get somewhat less confusing timings if you call glFinish() before glXSwapBuffers(). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
