I hope the Bluetooth audio latency issue I've been having is fixed. I have two Bluetooth pairs of headphones, one open-ear and one noise-cancelling, and they both have either a half-second or one-second latency between what happens on screen and the audio feedback. Luckily wired headsets work perfectly fine.
If you boot into desktop mode, you can check if switching to plain old A2DP works. That solved the issue on Ubuntu (and Windows) for me. I think audiophiles will lament the loss of audio quality, but lower latencies are much more important for gaming.
