Bug Report - AE 16.0.1 - Lumetri Scopes not displaying anything after some use.
When using the Lumetri Scopes, after having AE open for some time, the scopes themselves disappear and there seems to be no way to get them working again. I can close the scopes panel and reopen it and also try to change what scopes are displaying but nothing works. Must restart AE for them to work again. Problem typically occurs when changing from one composition to another.
Thank you for this bug report.
Are you also using external video preview via Mercury Transmit? (Preferences > Video Preview)
When the problem starts, try enabling and then disabling Mercury Transmit. You could also try pressing the / key on the numeric keypad.
(Under the hood, Lumetri Scopes captures the frame using Mercury Transmit. Although Transmit does not need to be enabled in the prefs for Lumetri Scopes to do this, I’m curious if toggling it on/off would help, or maybe there is a conflict with another Transmit device.)

Enabling Mercury Transmit didn't do anything for the scopes, but pressing the / key did.
I have the same problem!
I have not been using Mercury Transmit but will definitely give that a try! I will let you know if this helps or not the next time it happens.
