Strange white bubbles in the image
Hi there!
I have a DaVinci project (from a colorist from the past) and previously it was ok, but now I need some shots to replace and apply the colorist’s grade. I’ve done it easily, but then I discovered that some old clips have a strange overlay on it (some contours like white bubbles).
Here are the screenshots:

Those look like the original colourist was using external masks or something to hide something. Do they move with the picture, or are they static on screen.
(the guy in front of the vehicle looks like hand drawn shapes)The ones in the vehicle might have been a pimple removal or something like that.

Thanks for reply, Glenn.
The bubbles are indeed moving with the objects, but I’m sure they’re not hand-drawn masks (but maybe some color selection?). Anyway I don’t see a purpose for them. And there are no signs of them before – previously I had a clean export from this project, but now they renders out with picture. -
I’ve found out that it was because of the node with HSL. When I changed HSL value the bubbles overlay disappeared but the red color began looking pale.
Can it be some sort of maybe a safe mode for red channel which turns on? I wonder why this appeared in the rendered image now while previous rendered version from the colorist was ok. Could it be because of color management accidentally was changed (for example)?

Ok, it looks like a Davinci 15th version OFX plug-ins bug!
I loaded the same project in v14 and the problem is gone!
