            Bug ID: 250978
           Summary: Unexpectedly unloads images from Artstation galleries
                    (also, janky scrolling)
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK

On https://www.artstation.com/guweiz :

* When you scroll down the gallery, and scroll back up, you will notice that some images get "unloaded" and never show up again until you refresh the page.
* Scrolling is janky, not butter-smooth. Somewhat janky scrolling can also be observed on other gallery websites such as https://www.deviantart.com/guweiz/gallery

Demonstration video (Epiphany on the left, Firefox on the right): https://youtu.be/hcpZT8KPSKI

Observed with Epiphany 43.0 (WebKitGTK 2.38.3) on Fedora 37, with GNOME Xorg session and AMD open source graphics.

Firefox is not affected by these problems.
