@mntmn Recent versions of WebKitGTK with the new dmabuf renderer (which it shares with WPE AFAIUI) perform similarly well. It only needs some papercuts around touch input handling solved - I have recently worked on some, but there's a few more left.
@mntmn It's been there for a few releases already, though it was getting additional improvements over time. It's been snappy on the L5 in the last months. 2.52 has been released today, it's not yet in Debian (though 2.51.93 is in experimental), but should be soon and it looks promising too: https://webkitgtk.org/2026/03/18/webkitgtk-2.52-highlights.html
