@zaapa1 This looks like a browser specific issue rather than a system problem. Since it works fine on other browsers and older setups it may be related to how Opera on Windows 11 handles scrolling events. A quick workaround is to disable smooth scrolling or gesture settings inside Opera and test again. You can also try updating Opera to the latest version or resetting browser settings. If the issue continues it may be worth reporting it to Opera support with clear steps. In the meantime using another browser for this website seems like the most stable option.
