VB.NET Web Browser Youtube full screen not working - vb.net

I have been working on a simulation of windows 11, and it works, pretty well, but I added a web browser so you can browse the web and whenever i clicked on full screen mode on youtube, the video still shown, but the full screen part was all black.
This is the video fullscreen
Anyone have any idea how to fix this? I have been searching the web for it and I can't find anything.

html5 app freezes in ios13 after navigating to an external url in in-app standalone safari browser and back

Issue
My web application built using nuxt and installed as web app on iphone becomes unresponsive after I open or visit an external link from the app. Issue specifically comes iOS 13.4 and above on real devices. Simulators works fine.
Devices
iPhone X and XI (all versions) with iOS 13.4 and above
Steps to reproduce
Open url https://nuxt-min-pwa.netlify.app/ in safari.
Tap on share icon and then add to home screen.
Open app from home screen.
Tap on menu icon.
Tap on second.
Tap on link named ICE.
App will open an external url.
Tap on Back to App button to return to the app.
Tap on second now.
App does not responds. A thin loading bar seems to be in progress, everytime second is tapped. But nothing else happens.
Web app is working fine in iphone8 with ios 13.3.1 and Xcode simulators. There is a similar issue reported on both stack overflow and apple developer forum. Although it specifically mentions microsoft openid, but I am sure, issue comes up with any external url.

Whatsapp share link does not work in safari

I'm using this approach: https://stackoverflow.com/a/25796908/3437433
It works like a charm, but when I'm trying to use it in Safari (both desktop and mobile), then quite strange things happen.
On desktop, origin link https://wa.me/?text=123 is somehow replaced with whatsapp://send?text=123. And then Safari displays error page about wrong protocol.
On mobile, correct page is opened by origin link, but also alert appears saying "can't open page because url is wrong". I can close that alert, can click on "send" button, but then https://whatsapp.com/download/ page is opened, instead of prompting to login to whatsapp and redirecting to chat.
Does anybody know what's going on here and whether it can be fixed?
We usually differ link at desktop view and mobile view to offer support for safari and other browser.
for desktop view we use
https://web.whatsapp.com/send?phone=6200000000&text=Hello%20Moxqitto
for mobile, we follow whatsapp best practice https://faq.whatsapp.com/en/android/26000030/
https://wa.me/6200000000
Tested on
Chrome for mac
safari for mac
android chrome
Ps: not tested when mac have whatsapp desktop app, but it will still work in the safari itself. so it should be ok
Official Sharing Documentation For WhatsApp. They say to use their wa.me/... URL. Okay! So let's try it out! http://wa.me/?text=mytest For me, I get an error message...
PAGE NOT FOUND
However, these seem to work great for me!
https://api.whatsapp.com/send?text=YourShareTextHere
https://api.whatsapp.com/send?text=YourShareTextHere&phone=123

CefSharp embedded browser on .net not rendering Google StreetView

I have a Vb.Net WinForm Application with Cef Browser embedded onto this.
I use this browser to see Google Maps and Google Street View in the same app.
Use the Cef Browser because the embedded IE Browser gives me headache with the compatibility with the Google Maps JS API.
On almost all of the computers where the app is running, is running fine.
The problem is with one specific computer that can't render the Google Street View (Google Maps renders OK).
And it works on a normal browser like Google Chrome.
Here a Screenshot.
It's like it load only one picture, but when i move the camera it unload the picture and load another picture in the same place. Always one picture at the time. So weird.
I have no idea where to look for a solution.

Windows Phone device back button would quit the app, but not go to the previous page

I am making a Windows 10 Universal App with this tutorial. Everything works fine, but on a Windows phone, when a user click on the back button on the device, it would just quit the app. The expected behaviour should be going back to the previous navigated page. How can I handle this for my web app, probably using JavaScript?
Thank you!

Detect closing of mobile Safari

I'm building a WebApp which uses video server push with:
<img id="vidsrc" src="video.cgi"/>
It works. And when saved as a WebApp using "Add to Home Screen" closing the app does as expected and stop receiving the server push.
However when running in mobile Safari, only closing the page will get it to stop. What I'm trying to figure out is how to get it to stop if the user clicks the Home button and closes mobile Safari so the push doesn't keep running in the background.
Because of what I've got to work with, editing video.cgi is not an option. And using video.cgi in an iframe isn't a good solution because of some other functionality in the page/app.
onBlur and onClose don't seem to do it, and I'm wondering if there's any way an HTML page or the good stuff in it can know that mobile Safari has been closed.
Unfortunately, you can't... Web apps are not allowed to access the device's software, so are not told when you have pressed the button.
