@leocg tried disabling extensions, nothing changed
OS is Windows 10
version of Opera is the most recent, LVL 2 (core: 76.0.4017.208)

I've been liking Opera GX so far, but the other day I started having an issue where some pages would load fine (like YouTube, Steam, Twitch and others) but some sites will only load halfway (like Twitter, Patreon, and Fandom). I tried opening new tabs for them, nothing. I tried restarting, that did nothing, I tried clearing the cache, nothing. I'm ready to restart my computer next but I don't want to unless I have to. All of the bugged pages will stop loading like they finished, but they'll be missing most of the content or format.
