Moving text/object leaves trail after render

Hello,
I am not sure how to describe the issue, but you will see it on the pictures bellow.
I used Sony Vegas for a long time, but now i want to switch to some other editor. I tried to make my intro sequence in Davinci Resolve 17, rendered it, but the moving text leaves uggly pixel trail. I have exact same thing in Sony vegas, and there is nothing like that. It is completely nicely black.
Here are 2 screenshots, 1 from video and second one is edited, so you can see what i mean.
Can anyone help me? Not sure what i am doing wrong (tried mutliple rendering options).
Thank you

Using Occam's Razor, I want to check for Operator Error.

Have you completed any training for Resolve?

Hi, actually no i didn't, i tried different settings for exporting, which i found online, but result was the same

Check for illegal values with your scopes, many people forget this when using external graphics.
DR is assuming professional knowledge, while other programs may fix issues behind your back (and introduce other problems).
If that doesn’t help, try to export in a high quality codec like Cineform or DNxHR and see if it persists. If it’s gone, make your final version in Handbrake.

Its there even if i use HQ codec and even uncompressed.
Its just weird for me, that vegas renders same thing with h.264 without problem...

My guess is GPU

And can you please direct me a little, what i need to do to fix this?

For a start, tell us which one you have.

Here are my specs:
AMD Ryzen 5 3600
16 GB RAM
NVIDIA GeForce 2060 SUPER (8gb)

Just tried to download Adobe Premiere trial version, put my intro in and hit render with 264 codec. Outcome nicely black, no dead pixels. Seems like only DR has this issue.

Did you use hardware accelerated render? If so, try to switch it off and give it another try.
