Some webapps (Friendica) slow in Brave?

Unsure where to place this and how to track it down: I recently experienced “some” web pages (most notably the user interface of Friendica, a Facebook-style decentralized social network platform) to be in a weird way “slow” in Brave. The site is JavaScript-heavy in some aspects, and a lot of interactions, starting with actually scrolling on the page, behave the browser/page to stutter and feel laggy and unresponsive. This doesn’t happen in other Chromium based browsers or in Firefox on the same hardware. As poor as this description is; any ideas or inspirations how to even get an idea what’s going on here?
Thanks and best,

Hello @z428
Thanks for bringing this to our attention and sorry to hear you’re having trouble with Brave. Can you try disabling Hardware Acceleration in settings one more time, to see if this resolves the issue?

You’ll find this in Settings --> Additional Settings --> System --> Hardware Acceleration

Please, let me know if that works and have a nice day!
