Strange artefacts ACR 9.8

[TonyW]

I am getting these artefacts occasionally in CC 2017 ACR 9.8 associated with moving a slider or moving cursor in histogram window.

AFAIR there has not been an issue prior to last week.  It looks like it might be graphics or graphics preview issue and is a nuisance rather than a major issue.  Images render fine regardless of ACR preview looking like this.

I will look into graphics drivers just in case but anyone had similar and can offer a fix?

I do not know, but to install a new GPU driver(Windows) is better to use DDU
and allow it do boot in Safe Mode.

I think it exactly started with most recent NVidia GPU drivers pushed by W10 update...

in my case "NVIDIA - Display - 12/29/2016 12:00:00 AM - 21.21.13.7654" ... "successfully" installed 2017-02-12

Thanks guys.  Sounds highly likely NVidia driver.  I do not normally elect to have auto updates, but Windows 10 seems to laugh in the face of what I want on occasion 
Will check my updates and see if I can rollback the graphic driver

EDIT:  Yes that was it (at least I think so !) rolled back to the old driver and tested - no artefacts.  In case anyone finds this a screenshot of the rollback - red is the old(newest) green rollback to working driver.  I have also disabled automatic driver updates so that I can now choose if and when
