The return of the flickering plugins and graphic glitches

Greetings all,
Having just finished my new build (see below), I’m disappointed to see the return of flickering graphics (mainly seen on VSTi). I thought this had been fixed in 13.0.21 ??
Kontakt is particularly bad, although GA5 is not great. Haven’t yet checked every instrument.
Cubase 13.0.41 - Win 11
i9 14900k, Asus Z790e, 192GB RAM, RX6800 XT using latest Pro Driver (Q3 2022) Anti-lag activated - 2 x 4K Samsung 32 inch monitors at 60Hz

It’s much improved with the latest RX6800 driver. Driver only I might add, none of the other nonsense
