I used Epiphany 3.23.4-1.fc26 on GNOME Shell and Wayland with my Elitebook 8560w (nVidia Quadro 1000M NVC1). If I open some tabs, the screen began black entirely. I can see only the cursor. Or sometimes the computer freezes. But I can't move the cursor, I can't open a TTY session or other things. I need to reboot my computer in both cases. I don't have this bug with Firefox for example.
