No, I see this transparency just at the recorded video. I have the same problem with any dark windows even with different colors/themes and with Windows Capture too.Does this transparency only occur within your recordings, or is it present at the actual browser window too? Can it be that this is MS Windows (theme) behaviour?
It appears that you're not using a Window Capture source. Is that on purpose? If you do use Window Capture, does the transparency still occur?
Him...Are we really talking about transparency? IMHO i see just a "boxing" and bad-compression based issue: artifacts.
Are these issue blowing away each couple of seconds and fading slightly back in?
I had to reinstall my windows 10, the problem just solved!If it really is transparency, you should be able to see the difference between recording ie. this google window "as is" and the same window with something black behind it. Could you give that a try?
Creating "something black" can be done in various ways, ie. have a fullscreen presentation with black background, or have the attached image shown fullscreen.View attachment 77947
