The "older" UI is shown when detection that your graphics card has the
necessary OpenGL support fails. That includes a timeout. If your
machine is starting a lot of services at boot, and if your hard drives
are too busy loading stuff to run the test tool as quickly as they
should, this may happen. It likely won't be shown if you get a faster
hard disk. Clearly a bug though.
I'm not sure the speed of the HDD makes much difference. I've got a
SSD and on occasion I get it as well. I also occasionally get a fall
back to the old style dialog when logged into the desktop. One minute
I'll get the new one when I need to unlock a ssh key, the next the old
one when I need to put in some network details and then back to the
new one (not saying it's network, that's an example, can be any
dialog) when it's running g-s fine. Tends to happen more when the
machine has been up for longer.
