--- Comment #11 from David March <davidmarch007 at gmail.com> ---
I was able to initiate an apitrace when some textual corruptions (but not the
full menu corruptions which happen in the later stages) started appearing on
the plasmashell menus.  However upon playing back the trace it does not
recreate the issue so I doubt it will do much good?  If you still want it let
me know.  the trace is 4.3 GB and gzip is able to take it down to about 2.5 GB.

If you only need to see it to see what it looks like when the corruptions occur
then would some before and after screenshots perhaps work better?

Also I have found that after closing some applications and then doing 'echo 1 >
/proc/sys/vm/drop_caches' I can almost immediately restore proper rendering
again.  Next time I will test further to see if dropping caches always works
even without closing any applications.  If it does I would think that narrows
down what is going on with this bug and what is triggering it.
