VG279QM stuttering on ufo test

I just received this monitor.
The ufo test stutters in a fixed interval of 7 seconds since it occurs, always from 280 to 268fps.
Tested frame skipping with my phone and I think it's working properly.
I thought it was something in Windows so I did a clean install without touching absolutely no setting but same is happening.
Don't know if it's software, hardware or Chrome.
Happens at 280Hz, 240 and 144.
Have cpu and gpu at full frequency.

If anyone has any idea how I can find the problem I would appreciate it.

Try using a different browser.

Don't really want to install another browser just for this but Chrome should work just fine.
This is a clean Windows installation so it bugs me.

I get the same syncing failure or browser stutter(+1) with nothing open, tried on Chrome, Edge and FF.

You have VG259qm right?
Since you tried FF, it's not the browser.
I tried Nvidia older drivers but it's not it.
Unless something changed in the ufo website this is a problem with the monitor (both sizes) or Windows by some update.
It was happening with 21H2 and I made a clean install with 22H2. If it's Windows must be prior to those.

Had the same issue recently with another monitor. In my case it was because hardware acceleration in the browser was off. Turned it on and it was smooth, just a tip :)
