Folder icons randomly acquire black background

Anyone noticed something strange happening in Windows 10. For some reason some of the folder icons seem to get a black background. I've no idea why this happens, it seems to be random. (see screen capture)

Resetting the icons back to 'normal' is a bit of a bind Right Click->Customise->Change Icon->Reset defaults
and each has to be done individually as selecting multiple folders does not work.

Anyone any ideas why this is happening and how to stop it?
and have a quicker way to reset the folders to 'normal.

No ideas why.
You could try to rebuild the iconcache as described here:

Also try running System File Checker.

Open cmd.exe with Run as Administrator and run SFC /SCANNOW twice. Allow to complete. Shut down (power off), start up and test.

Make sure all Windows and Office updates are current.

Also upgrade or reinstall your video driver and chipset.

Ran SCF /SCANNOW and it found some errors and fixed them, but the issue is still happening,
Acronis True Image 2019 just released!

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

Did you try upgrading / reinstalling the Video and chipset drivers?
Brian PiercePhotographerAuthor Commented:
Removed the video driver and re-installed - made no difference
BTW rebuilding the icon cache does nothing either.

The only way I've found to remove the back background is to Right Click on the folder and select Customise->Change Icon->Reset defaults... and you have to do it one folder at a time.
JohnBusiness Consultant (Owner)Commented:
Try a plain colour background and classic theme - no aero or eye candy and see if that helps.
Apologies, I confused icon cache and thumbnail cache:
In someone reports that fixed it for him, and it was recommended by Brink who can be trusted.
