Looks like a dup of https://bugs.freedesktop.org/show_bug.cgi?id=28341

If you agree you could change the status of this bug to dup.

If you pull today's git mesa master you should be able to workaround by running
the apps with the env var vblank_mode=0 set, so try -

vblank_mode=0 etracer

It doesn't work for me from ~/.drirc for some reason.

You should still get a different sort of vsync, but only when full screen.
