This is a very interesting problem. If you're seeing this for images as well as HTML, it implies that hosting of the Web Browser Control is entirely broken. I'd be curious to learn if that's true for all clients (e.g. try https://bayden.com/dl/dotnetbrowser.exe
) or whether the problem is somehow specific to your system.
Inside IE's Tools > Internet Options > Advanced tab > is "Use software rendering instead of GPU rendering" checked?
Unfortunately, I can't think of any good steps you might use to troubleshoot this, short of updating to the latest WindowsInsider build and seeing whether that fixes the problem.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
