Some windows cannot be captured

[susch19]

Description of Issue
I tried capturing different windows on my system, but some of them seem to not work.
Capturing the complete desktop works and the content of all applications is displayed. Only capturing the windows on it's own results in a complete black or white window.

For example Opera while writing this issue

Tested and not working
Chrome, Firefox, Edge, Opera, TeamSpeak, Task-Manager, VisualStudio Code

Tested and working
Telegram, Windows Explorer, Google Play Desktop App, Thunderbird, Keepass, VisualStudio, OBS

System Information
Unity 2019.3.6f1
Windows 10 Pro Insider Preview Build 19577.rs_prerelease.200228-1439

Other Information
I have tried the different properties for capturing in different combinations, but all have the same result. I also only tried your examples

As soon as i disable hardware acceleration for the web browsers, it works. Dont' know if this is fixable. I guess the buffers are different in this case, so capturing is limited.
