Creative Vignetting does not work unless Vignetting (correction with DXO module) is disabled. I assume this is a bug and not intended behaviour as it wasn’t an issue in PL3 as far as I can remember?
I’m not having that problem.
I’m on the MacOS version. Are you?
I’m on macOS Catalina and don’t have a problem using both at the same time.
After a reboot all seems to be well. Hopefully just a glitch on first use. Thank you all for your feedback.
