WebView2 White Flash On Hide

[Jacob Penn (jakepenn)]

Hello! I'm using a WebView2 embedded inside a JUCE application via their framework level solution, however I believe this issue stems from placing a WebView inside a native window. When the WebView is first created, I correctly see my default background color as intended, however in my application I'm using both native & WebView driven windows.

When hiding the WebView2 component, I have a white flash which I'm unable to to address, it appears to be a part of the WebView layering itself. In order to solve it I've needed to render a secondary window matching the WebView before hiding it. I have the experience of a white flash when transforming the bounds of the WebView or any other changes to it which cause a flash behind its components.

Has anyone else experienced this issue of a flash when hiding a WebView? When showing it it's fine.

Thank you!
