taskbar and webview window disappear

[jinnyum]

Description
Sometimes the webview2 window, window taskbar disappear.
At this time, I was watching YouTube in another browser, and in that browser, everything except the video disappeared.
(Everything from the browser address display to the tab bar title display)
This also happens when move the mouse in the web view and when resize the web view window.
This is a phenomenon I have never seen when not using webview.
I do not know if this is due to a bug in webview or not, so I inquire.

Hey @jinnyum - this doesn't sound related to WebView2, but may be a graphics driver issue. Are you saying you saw this behavior in a WebView2 app that was playing a youtube window? Or just that a WebView2 was open in a different app when you noticed the issue in your browser?

I am working on watching youtube in webview2.
At this point, a problem arises.
In a normal browser, there was no problem with watching numerous YouTube videos at the same time.
This phenomenon only occurred when watching YouTube videos in webview2, so I inquired.
For reference, here are my graphic specs.
NVDIA GeForce RTX 2060
Driver Ver : 27.21.14.5763
If you see this answer and you still think it's a graphics issue, please close the question.
(There is a problem, and I do not know if this is a graphic driver problem or a webview2 problem, so please understand that I had no choice but to ask.)

You should definitely feel free to ask :) Even if it is a drivers issue, we can take a look and see what may be happening. Have you tried your scenario on a different machine, or checked for driver updates? I've added this bug to our backlog. Thanks!
