I just want to share that I see exactly the same problem: a window shows
up, immediately get deleted, and this repeats after a very short while.  My
lspci shows the following:

It is not a nVidia, so the problem is not specific to one card.  Output of
etr, if I run it on the command line, looked like this:

kkto at resinken:~$ etr

That is after I manually disabled pulseaudio and started jackd so that the
jackd error doesn't show up.  I tried to run it over strace, and I see lots
of EAGAIN.  Around the first one I see this:

I'm not sure what is going on.
