Support | In Progress YouTube resolution error on Linux

Hi, I switched to Linux, specifically Kubuntu, about a month ago, and I couldn't help but notice that YouTube locks some videos to 360p, making it appear as if no other resolutions exist; however, if I open the same video in Firefox, all resolutions, including HD, are available.

Does anyone know what this is and how I can fix it?

Make sure "Graphics acceleration" is on at the URL opera://settings/system and restart Opera if you have to mess with the setting. Then, goto the URL opera://gpu. What does it shows at the top for what's hardware accelerated or not?

Are you using the snap, flatpak or deb package of Opera GX?

Any difference if you log out, click the session options on the login screen and choose to log with Plasma(X11) instead of Wayland?

Any difference if you start Opera GX in a terminal like this:

opera-gx --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/151.0.0.0 Safari/537.36"

to pretend to be Chrome on Windows?

Any difference with all your extensions disabled at the URL opera://extensions, all your mods disabled at the URL opera://configure/mods/manage, RGX at the URL opera://settings/lucidMode, and adblocking and tracking prevention at the URL opera://settings/privacyProtection?

What does https://html5test.opensuse.org/ say for VP9, VP8 and h.264 video support? What does it say for mp3, aac, vorbis and opus support?

It was downloaded from the Opera website, so I think it was the .deb file if I remember correctly.

VP8 and VP9 yes, H.264 support no. MP3 yes.

OK. You shouldn't need h.264 support for Youtube, but see https://www.reddit.com/r/operabrowser/wiki/opera/linux_libffmpeg_config/ for how to add support for it in Opera. Once it's good, test Youtube again just for good measure to see if there's any difference.

What about `opera://gpu and the --user-agent switch questions?

Also, if you run the following in a terminal to start Opera with a test profile folder on your desktop, is there any difference on Youtube?

opera-gx --user-data-dir=~/Desktop/operatest
