The Grey Bar is back on 2.0.68.
If you start in full screen landscape mode and have it set to load the first camera group (Or any camera group for that matter)... The Grey bar is back on the top.
I'm able to clear it up, if I rotate to portrait and rotate it back. Usually not an issue on my phone, but on a mounted tablet, not so much.
I can confirm switching the bit rate did speed things up, thanks for that tip.
