Opera has recently removed good features. I loved the quick search, now I have to open a new google tab to search when you could do it in seconds, just clicking at the left side of the bar. I know that they could have do it experimentally, but It's a mess and they haven't returned one of them yet (as far as I know). However, I hope these changes aren't permanent.

He estado mirando los foros a ver si hay alguna información sobre ese posible modo oculto en el navegador común de Opera, aunque no he encontrado nada "oculto". Pero dudo que la haya, ya que entonces también lo habrían implementado tanto al Opera GX como al Opera común, puesto que no creo que se distingan mucho.
De todas formas, el "forzar modo oscuro" de GX está en BETA como sabrás y no es muy bueno del todo a mi parecer. Te recomiendo que instales extensiones, como Dark Reader o Night Shift que son de Google pero con el Opera add-on de extensiones de Chrome las puedes obtener, o simplemente en los propios addons de Opera ya hay extensiones que hacen el mismo trabajo, aunque no he probado ninguna; sólo las dos que he mencionado.

Do you have an extension that obligates white colors turn into black? I'm asking this because I use this kind of extensions (like Dark Reader) and when I visit certain pages, something that is white turns into black and vice versa. In my personal case, Dark Reader doesn't do that with Youtube videos, so check your extensions in order to see if some of them is causing the issue or it's interfering with other add-on.

Oooh, it's true that my first thought was the "force dark pages" mode of Opera, but I didn't mention it because this problem was posted in "Opera for windows" and not in "Opera GX", so I didn't consider it. However, you're right: I've used the force dark pages mode, but; as you've said, it's a BETA mode and it doesn't work properly. That's why I don't use it. Anyways, I'm glad that the problem has been resolved. You should try other extensions like Dark Reader or Night Shift, they work very well for darkening pages, and you can obtain them with the "install chrome extensions" add-on. Nothing more to say, have a great day too.

Hello, I don't have any idea of how to solve this in an effective way. But, it could be due to many factors, like the headphones (as you've posted), your PC configuration or the particular browser. From my experience, I can say the audio in Opera sounds lower and I have to increase the volume of my PC to almost 100. However, when I use my headphones (it's mark is Tritton), the audio it's better and I'm able to decrease it to 30. I think this is primarly because of my PC, but it's true that in Chrome the audio seems to be in a better quality (just a bit, though). I'd recommend you to configure the sound configuration of your PC, and try various options and variables.

@mohid Alright, I'm seeing the problem. You are using the Opera's VPN while @saturnxing and I are using the VPN of Opera GX. I imagine that in Opera browser there's no way to change the region of the VPN, while in Opera GX; yes. Sorry, but I gave a quick solution that it seems to work only in Opera GX. This confusion has happened because I answered to this topic in the Opera GX forum but the moderator moved it to Opera browser forum; so I'm not suppose to be here, haha. However, I hope there's another way to resolve this.

@jeezara Are you sure that this option doesn't appear in your VPN? Have you clicked on it?

@saturnxing Oooh, that's good. You're welcome

Hello. I've just tried with my VPN. Initially, I had the same problem; it was yellow and it wasn't connecting. However, when I used the Asian VPN, everything started to go well. I don't have a clear and succesful solution, but you should test to change the region of the VPN constantly. That worked with me.

Hello. You're saying that your problem have been occurring since your windows 10 updated to the version 2004. Doesn't that mean the issue is due to Windows and not Opera? Try to restore to a previous Windows version.
Go to Window's configuration>Update and Security>Restoration/Recovery.
That's the only solution that I have in mind. I hope your problem to be resolve.

@greggo20 Bueno, que una extensión o app quite las imágenes creo que es más sencillo que lo de las jergas. Quitar imágenes sólo se basará, probablemente, en detectar en las páginas web archivos .png, .jpg y similares y suprimirlos sin más. En cambio, el lenguaje es muchísimo más complejo y está sujeto a todo tipo de variedades, sentidos figurativos, etc. Así que para una extensión le va a resultar mayor trabajo detectar las palabras y comprender qué jerga es y por cuál sustituir; entre otras acciones pertinentes. Sin embargo, no creo que sea imposible; y si no hay aún ninguna que lo haga; la habrá pronto.

Hola, sobre lo que cuentas dudo que haya una forma para ello. Es cierto que Opera ofrece numerosos dialectos del español en su sección de idiomas como español castellano, argentino, etc. Sin embargo, esto sólo sirve para que las funciones de Opera salgan con dicho idioma. Por otra parte, las páginas mantendrán el idioma y la redacción con la que fueron escritas sin modificación alguna. Se podría traducir la página, pero tampoco serviría para mucho. Si estuviera en un idioma que no fuese español, el traductor lo transcribiría a español (ya que no hay diferenciación de dialectos en los traductores como el de google). En cambio, si estuviera en español de por sí, sería innecesario traducir español a español. Desconozco si hay alguna extensión que lo haga, por lo que investigarlo sería útil. Aún así, algo como una jerga, los traductores suelen tener errores. Alguna palabra característica de la jerga podría ser detectada y cambiada, pero no siempre sería infalible y da lugar a errores de traducción.
Saludos.

I also think it's not possible. But, from my experience using it, you should try to check that pages that you don't want to be refreshed in intervals of 10 minutes or something like that. For example, you may check Hangouts each 10 minutes and, if I remember well (because I don't use GX Control since long time ago), that will prevent the page to be refreshed.

Same problem here. It seems like Youtube can detect or interfere with Opera's adblock. So, I recommend you guys to install another adblock instead of Opera's. I'm using Ublock and now these white screens don't show up anymore. But, it's true that sometimes I've had that annoying white screen even with Ublock. However, it's something occasional.
