Same problem with Sony WH-1000XM2
My workaround is
1. Turn on headphone, wait to connect with low quality sink
2. Turn off bluetooth, wait couple of seconds and turn on
3. Reconnect headphones.
Works all the time.
Ubuntu: 18.04
Sony WH-1000XM2

You received this bug notification because
started happening with kernel 4.12.0-rc
if I plug in an external screen, configure the layout, than when I
disconnect and reconnect the layout is reset to the default.
if I boot back to 4.10.X all works fine.
