Created attachment 291713 [details] lsmod, lspci and installed packages When I start epiphany 3.22.1 under wayland there are a lot of video glitches that make impossible to see the window content. Using the flag GDK_BACKEND=x11 that bug do not happens. That bug is happen on a desktop with a radeon rx 480 with fully update open source stack, mesa, amdgpu, kernel 4.8, gtk 3.22.1 and webkit2gtk 2.14.1. It not happens on a notebook ivybridge with intel video driver. Using the flag GDK_GL=disable just the webview shows that glitches. I'm using fully updated Arch Linux. There isn't backtrace on gdb. Step to reproduce: 1 - open epiphany on gnome 3.22 wayland on amdgpu stack;

OK, Márcio discovered in the GNOME bug that this issue affects Totem, so it's definitely not a WebKit problem.
