I agree, I have a similar problem with a Helios 44M-7 lens. It may be a reflection from the multiple coatings of the lens. Does the software in a Panasonic camera correct this, and YMMV when using a Lumix lens on a non-Panasonic camera?
Here is a shot from my vintage Zenit MC HELIOS 44M-7 58mm f2 with a Fotodiox M42-EOS(V2) adapter on a BMPCC4K. This is the MC (Multi Coated) version of this lens and is supposed to have better veiling flare resistance than the earlier versions. The flare on this lens is interesting but I did have significant purple CA on the tunnel wall against the blown out outside entrance that I removed most of in Adobe Lightroom. Look for it behind the sillouetted woman.

Here is a 1976 Helios 44-2 58mm anamorfake lens with a fixed oval aperture of F/3.5 and a string for flaring compared to the 1993 Helios 44M-7 with it's MC coating. Again, using a DEC Lensregain EF to MFT focal reducer to mount it to a BMPCC 4K. I used a lot of dehaze in Lightroom to bring out the colors. Drag the image to reveal the one to compare it with underneath.
