Expected Behavior

Source displayed correctly after redirects.

Current Behavior

Redirects seem to confuse the browser source, and end up with an invisible source. Editing the custom CSS, e.g. tweaking body { background-color: rgba(0, 0, 0, 0; } between rgba(0, 0, 0, 0) and rgba(0, 0, 0, 1), the source will briefly flash visible then disappear again.

In this instance, the source is a page that does a redirect to Spotify for auth before redirecting back. If I relaunch OBS, where the auth has happened, so that a redirect isn't required, the browser source displays fine. Refreshing cache, making source enabled/disabled does not fix it, only relaunching OBS.

Steps to Reproduce

Add a browser source which does a redirect on load, e.g. https://jessicah.nz/spotify/now-playing.html

Anything else we should know?

There is definitely something very weird happening here. The page still renders in devtools but not in OBS

Forcing the page to navigate to another URL such as Google and then issuing a history.back() command the page then functions fine.

I have the same issue on my own implementation of cef. this happens only when using external_begin_frame = true and the browser_id > 1. if the browser_id(1) is navigated or closed, the issue is fixed. Navigating browser_id > 1 will stall the video capture until navigated back or the browser_id(1) is navigated or closed.
As a temporary workaround, at initialization im creating a browser instance and killing it right away.
