Hi,
What's the build version you have installed? You can run "winver" to show the OS information.
Please try to install the latest version 19041.572 to see if the issue could be resolved or not.

In the previous builds, there are several known issues about visual distortion or browser.
For example, in build 19041.388, it updates an issue that might cause certain games and applications to have visual distortion when resizing in windowed mode or switching from full screen to window mode.
And in build 19041.423, it addresses an issue in Microsoft Edge IE mode that occurs when you open multiple documents from a SharePoint site and an issue in Microsoft Edge IE mode that occurs when you browse using anchor links.
Thanks,
Eleven
