Thanks for your testing report! However, I'm not sure I understand your steps....
Did you start with a completely clean install of the nightly (e.g., no old settings files)? Do you see different behavior when using TL?
Sorry if I was not clear.
INITIAL STATE: absolutely clean nightly after card formatting.
Turn on the camera. Turn on RAW recording with GD Allow. Several recordings go fine.
Then just switch recording from RAW to Standard. Recordings go fine as well, nothing changes.
Then I switch back to RAW recording (1584x892), making sure GD is set to Allow.
Now the GD during recording of RAW video starts to disappear. At first all texts and GD is gone, then the stripes disappear, so that while recording you do not have HD aspect ratio. It's a clean screen basically, with a camera sign and timer.
And yes, TL behaves the same way (( But if I use raw_rec not mlv_rec, this problem does not exist.
Another glitch: when zoomed x5 the screen flickers, when x10 it is ok, Have to turn zoom x5 off to avoid that. TL has slightly different glitch -- it is not flickering, it just goes b/w with an ugly low resolution, only x5 zoom.
