@BertGroner Ich habe es gerade mal bei mir ausprobiert mit www.n-tv.de. Bei mir hat es problemlos geklappt mit aktiviertem Ad- und Trackerblocker.
Hast du vielleicht noch etwas in den Einstellungen geändert, das das hindern könnte, dass es bei dir geht?

@ahmetissin I guess almost no browser shows subtitles on video pop-out, due to DRM limitations

Same thing happen in a test standalone installation

but after a while, the tabs close automatically;

Strange. ctrl + w is the keyboard shortcut that closes a tab. Alt + F4 can close the Opera window. Make sure you're not accidentally triggering those. Also, if possible, test with a different keyboard for a while.

Are you on Windows?

If you have anything enabled at the URL opera://settings/gx_lights, try disabling everything and restarting Opera to see if it helps.

You can try disabling the "hardware media key handling" flag at the URL opera://flags/#hardware-media-key-handling. to see if it helps.

Do you have any extensions installed at the URL opera://extensions?

Make sure RGX is off at the URL opera://settings/lucidMode.

If you have and shaders enabled at the URL opera://settings/shaders, disable them. Same for web modding at the URL opera://settings/web_modding. Also, make sure you're not using any limiters in the GX Control sidebar panel and make sure the battery saver is disabled at the URL opera://settings/batterySaver.

Make sure "graphics acceleration" is on at the URL opera://settings/system.

You can try messing with the Angle flag to see if you can avoid black while keeping VSR.

However, VSR could just be broken in Opera at the moment.

You can also try disabling Early Bird at the URL opera://settings/early_bird if you have it on.

Where is it? "New window instead of new tab"

@Janijan

It may not resolve immediately. It did not for me, and I left it as it was. It resolved the next day or two.

@Squeaker98 What OS does it use?

@Edo-line Collecting lots of old pieces of media online or at the store (mainly cds and dvds), and the occasional sailing (😉) across the internet.

@luisca Very wise of your bank. I can no longer trust this browser to do what you set in settings' having lost 40 plus tabs and 8 workspaces in an auto update that clearly was different to every previous update on 23 July.
