OS: Mac
I am specifically referring to video pop out during Google Hangouts calls, as that is the feature I frequently use.
Previously, the feature was working as-intended, if I switched to another tab during a call, a little box would pop out so I could still see the call while being on the other tab. Yesterday, I hooked my computer into a second monitor and pulled the entire tab with the call onto the second monitor and used that, without the pop out. Today, I am back to one monitor, but when the video should pop out as a little box, it instead creates a new fullscreen tab that is just the popout. It still has all the settings, such as opacity, but since there is no screen behind it that just makes it dim. There is no Enter/Exit Fullscreen button on it like most Mac applications have.
Making the Opera GX browser itself not fullscreen Does also make the popout not fullscreen, and I can resize it then, but it appears taking up the whole screen and I have to manually adjust it smaller. Closing the popout and reopening it reverts it to its original massive size.
I don't know what went wrong, bit I am looking to get back the original functionality of the popout feature, with the small box appearing in front of the page I moved to.
