Falkon browser poor performance - eviltoast

I do quite like the look and use of Falkon and would gladly ditch Firefox for it.

But page load times seem pretty bad.

When I use the scrollbar to move a side up and down, it seems rather sluggish or even lagging.

And the Lemmy website interface does not seem to work at all in Falkon. It keeps loading for a very long time or forever, and once it loads the new content from a new page, it still displays the content from the previous page at the top. Falkon also makes these weird orange borders around the main area of any Lemmy page when I click anywhere inside it.

It feels like a broken mess, and since I don’t think anyone would recommend a browser like that, I feel that there has to be something broken on my end.

I’m running Fedora 38 with KDE on my computer. If Falkon runs well on any computer, this one should be one of them. Any idea what the issue might be?
