artifacts on a horizontal line

Hello,
on images with contrasting horizontal lines I have artifacts the lines are distorted.
This problem appears in reading in the timeline, the original plan is correct, and I find it for export.
I have DaVinci 15 free final version on MacOS

Can you review this and provide details

HI, sorry I forgot the technical specifications.
I use DaVinci 15 free final version on MacOS

Please provide a lot more detail.. all we can guess now is its your system, OS or clip.

My guess would be a Mac'Pro' with the D700 GPU. Right?

Hi i have MacBook Pro (15 pouces, mi-2012) with 2,3 GHz Intel Core i7 and 16 GO ram. I use MacOS High Sierra

Probably your GPU is underpowered, but you didn't tell us this important detail.

the gpu on my mac is NVIDIA GeForce GT 650M.
I do not understand, I'm willing to admit having this problem when playing in the timeline, for real-time display, but when rendering to export everything should be recalculated, and I should not find this default.
Default that I do not find on the Adobe suite for example (premiere, AE)

Resolve is more demanding on hardware, please check the config guide.
What is the codec and resolution?
