Same issue on macOS Safari 18.1.1 when using the same server.

I have this issue on Element Desktop on Windows too. It's constant, and could be extremely dangerous for someone with photosensitive epilepsy.

I highly suggest that a warning be put on the app for folks with epilepsy until these UI issues are hammered out.

I'm not going to keep linking things because it looks like there's over 1200 issues mentioning scrolling, the X-Cannot-Reproduce tag added to this ticket is brazen considering this fact.

Sidenote: full clearing cache usually fixes that so my educated guess would be screwed up localstorage data about various things about events, positions, inserted/reordered events, and possibly relate-to pointers. And it keeps happening.

Will be fun to figure out.

I think the thousands of warnings could be produced because in your Element Web config theres still some keys that are written with camel case, like phasedRollOut and others.

I guess it is done on every time it checks the config for something, but this makes reading the console very hard even if I hide all warning logs.

The warnings also link to this page: https://github.com/element-hq/element-web/blob/develop/docs/config.md#-deprecation-notice
