Internet Explorer background color change

[Chris J LaBoda]

I am running IE 11.039.17763.0 and Dahua a Dahua NVR5216-16P-4KS2E Version V4.000.0000001.5 Build date 2019-12-06.

A few days ago the background main menu color changed to white. Rebooting the NVR changed nothing.

Any ideas what may have caused this? Everything is working fine otherwise.

After a few reboots of the NVR and computer it's back to normal.
