Screenshot

Visit https://apps.gnome.org/ in Epiphany Tech Preview (currently using WebKitGTK 2.48.0) and hover over any app tile. The rendering of the tile will become corrupted, and then WebKit will crash in Skia. The attached screenshot shows me hovering over the top left app tile.

Here is a truncated stack trace. Full stack trace is attached.
