Does anyone know if this type of rendering in RDKIT ver. 2020.03.3.0 is normal

Please see the screenshot below,

I am wondering if the carbons at the top of the structure is normal in RDKIT. The SMILES is CCC(CC(O)C(C)C1OC(=O)/C(C)=C\C=C\C(CC)C(O)/C(C)=C/C=C/C=C/C=C/C=C/C=C/C=C/CC2CC(O)CC(O)(CC(O)CC(O)CC(O)CC(O)CC(O)CC(O)CC(O)C(CC)C(O)C(C)C(O)C1C)O2)OC1CC(O)C(N(C)C)C(C)O1

Thanks

RDKit will depict an explicit C atom when the are neither multiple bonds nor substituents that help showing the presence of a carbon atom, and the two contiguous single bonds are almost collinear, making it very difficult to figure out that there is indeed a carbon atom in between the two bonds.
If you switch to the CoordGen depiction you will get a nicer layout that does not require those explicit carbons as it has 120 degree angles between sp3 carbons:

from rdkit.Chem.Draw import rdDepictor
rdDepictor.SetPreferCoordGen(True)

Thanks a lot! It looks awesome!
