menu cursor lag in PS 21.2.2

So like every single other human being on Earth, I was using the PSUserConfig file with "UseSystemStylus 0" and "TransforProportionalScale 0" which has fixed the various bugs that Adobe haven't been able to fix for as many years as I can remember. 

Since 21.2.2 we have been forced to disable the config file in order to get brush sensitivity. But now the dreaded 'lag' or 'snag' is back and without the config file I have no way to rid myself of it. It's easy to reproduce. Simply open a menu with sliders (e.g. brush panel) then use your wacom pen to move the slider - it will stick/lag/snag to the initial point then snap to the cursor location after either a period of time or ditance (I've never been able to work out which it is). This lag doesn't occur using wintab, but has always happened when using the dreaded Windows Ink. Despite me disabling as many Windows Ink settings as possible in Windows, I still get the lag. Of course the lag is not present when using a mouse. 

As an industry concept artist I cannot work with these lags. I need a fast and nimble workflow. 

Any suggestions please?

Wouldn't it be lovely if Adobe could test their updates even just a tiny bit before release?
