Hey! This issue likely comes from missing or outdated media codecs in Opera. Even though Opera and Brave are Chromium-based, Brave includes more built-in media support by default. Try updating Opera or reinstalling it via a Flatpak or Snap package, which often includes the needed codecs. Also, ensure hardware acceleration is enabled in Opera settings. That usually helps with resolution issues on YouTube.
