I read the whole thread to collect all testimonials to make sense out of this. It all leads to what I said: FreeSync.

He is the thread owner.
TF 80/100 works for me. In ufo ghosting test there is a slight purple corona but not in games.

Last sentence matches what you experienced.
Notty wrote:TF 80 - overshoot on every colour, eyes hurt just by dragging windows
This is relevant because when I drag a window even with TF 100 there is absolutely no inverse ghosting on the window itself, only the text is blurry.
If I disable FreeSync, the window will get a bright light of inverse ghosting like the mouse cursor.

He didn't mention if FreeSync was enabled.
I experience this in game with FreeSync disabled. TraceFree 100 is unacceptable.
"found out its not working on gsync and above trace free 40 its cause ghosting/overshoot/trailing"
"i ask twitch streamer that have this monitor https://www.twitch.tv/soulmercs
he told me gsync not work on this monitor and default could be 60 but its cause ghosting so he reduce it to 40"
He mentions on both sentences that gsync doesn't work and above TF 40 it causes overshoot. This happens precisely because FreeSync wasn't applied.
You should also take into account that Prad reviewed this monitor and they said that FreeSync resolved many of the image issues. Since you trust Prad, this should be enough to convince you.
These are google translations:
"We recommend to operate the VG258QR at 165 Hz and "Trace Free" 60, since excellent switching times are already achieved with these settings and the image is displayed without any blemish
and an almost ideal brightness progression."
"60 Hz without
Trace Free should be left here in the default settings to 60. An increase of the value conjures as a receipt violent corona to the object edges."
60 or 165 I don't think it matters, what is relevant is that this fits with the testimonials and what I said.
aberrations at maximum trace free of 100% and disabled FreeSync express much more than when FreeSync is activated."
"Violent image errors in "Trace Free" 100 and disabled FreeSync"
"Barely recognizable image errors with "Trace Free" 100 and active FreeSync"
"In the left image you can see the strong contrast jumps and the corona very nicely, which are almost absent on the right image when FreeSync is activated. Of course, even with FreeSync enabled and the highest overdrive level enabled, the image is not always bug-free, but quite an option for players who value performance more than a completely impeccable image."
