Debug log (no colors)

Debug log generated with this command:
$ LC_ALL=C gst-launch-1.0 -e ximagesrc ! vaapipostproc ! v4l2sink
device=/dev/video1 --gst-debug="*:5" --gst-debug-no-color &> ximagesrc-slow.log

I can confirm this bug. If I use use-damage=false the CPU usage is similar, but
frames doesn't seems to be dropped, no timestamp errors when reproducing.

I can confirm this bug(In reply to Edward Hervey from comment #3)

Performance is bad and you're right probably.
