@leocg,
Tried that before, no change whatsoever

@leocg,
Yes, they open perfectly fine both on a normal tab and on other browsers, I use Opera GX

My sidebar apps recently haven't been working properly, Spotify only shows the top inch or so, Instagram posts don't show and the messages have a strange outline, and ChatGPT and Discord just plain don't show. (screenshots of problems attached)
My Opera version is up to date, I've cleared my cache, I've disabled and enabled 'show sidebar', and disabled and enabled individually every app causing problems.
