CRT image jitters, especially in white areas

I have 90s Samsung CRT which has a jittery image, especially in the areas that display white.
I have fully recapped the deflection areas + neckboard + power supply (except the huge filter cap).

The whole screen jitters but it's more visible on white areas.

Turning down the contrast does not help.

Model is CK 3351X, schematics are available here: https://elektrotanya.com/samsung_ck3351%2C5051%2C5314~p68s.pdf/download.html

Any ideas? Thanks
