Created attachment 472813 [details] Sysprof 47 capture launching MiniBrowser I found another situation where Epiphany 47.0 / WebKitGTK 2.46's MiniBrowser has slow scrolling performance even with the Skia version, on Intel Kabylake "iris" graphics on Fedora 41's Wayland GNOME session. The test case is simply to load https://tabib.ca and scroll up and down a little bit with the touchpad (i.e. so that the big main banner below the navbar moves up and down). Attached is a sysprof capture with WebKit marks.
