Description Jeff Fortin 2024-08-26 19:27:55 PDT
On any computer (with Intel Kabylake graphics on Wayland, and open source AMD radeon R9 270 graphics on Wayland), with MiniBrowser and Epiphany TP (nightly flatpak), when scrolling through any search results on Hotels.com (ex: search for hotels in New York City for one or two guests for one night on some calendar date a couple months in the future), I am observing:

* Sluggish janky scroll performance as images load, with Epiphany TP (Vulkan Intel and nGL radeon) and MiniBrowser

* Epiphany TP (Skia, WebKitGTK 2.45.90 + GStreamer 1.24.7 + GTK 4.15.6) unloads the images as you scroll down, i.e. if you scroll back up they will have to load again; MiniBrowser does not seem to unload images once they're loaded, however. This sounds similar to https://gitlab.gnome.org/GNOME/epiphany/-/issues/1956 but in this case here I do *not* have the "Website Data Storage" setting turned off in Epiphany. Epiphany 46.3 (WebKitGTK 2.44.2 + GStreamer 1.24.7) does not seem to unload the images, only TP does.
