if I run epiphany in Fedora 24, I see warnings like: $ epiphany Gdk-WARNING **: gdkwindow-x11.c:5550 drawable is not a native X11 window Gdk-WARNING **: gdkwindow-x11.c:5550 drawable is not a native X11 window GLib-GObject-WARNING **: invalid cast from 'GdkWaylandVisual' to 'GdkX11Visual' Gdk-WARNING **: gdkwindow-x11.c:5550 drawable is not a native X11 window GLib-GObject-WARNING **: invalid cast from 'GdkWaylandVisual' to 'GdkX11Visual' Gdk-WARNING **: gdkwindow-x11.c:5550 drawable is not a native X11 window GLib-GObject-WARNING **: invalid cast from 'GdkWaylandVisual' to 'GdkX11Visual' Gdk-WARNING **: gdkwindow-x11.c:5550 drawable is not a native X11 window GLib-GObject-WARNING **: invalid cast from 'GdkWaylandVisual' to 'GdkX11Visual' Gdk-WARNING **: gdkwindow-x11.c:5550 drawable is not a native X11 window ** WARNING **: Failed to connect to UI process: Could not connect: Resource temporarily unavailable ** WARNING **: Failed to connect to UI process: Could not connect: Resource temporarily unavailable It seems to be trying to use X on a wayland display.

(In reply to comment #0) > Might be related to the fact that Fedora 24 is built with ENABLE_OPENGL=off > since the problem doesn't happen in rawhide with the same version (but has > opengl enabled) This code in webkitWebViewBaseRealize is wrong: #if USE(TEXTURE_MAPPER) && PLATFORM(X11) && !USE(REDIRECTED_XCOMPOSITE_WINDOW) if (DrawingAreaProxyImpl* drawingArea = static_cast<DrawingAreaProxyImpl*>(priv->pageProxy->drawingArea())) drawingArea->setNativeSurfaceHandleForCompositing(GDK_WINDOW_XID(window)); #endif You can see it improperly casts the GdkWindow to a GdkX11Window without checking to make sure it's X11. And I see it's guarded by USE(TEXTURE_MAPPER) so it's indeed not enabled by default, that explains why it works in rawhide (where I reenabled USE_OPENGL after our recent bugfixes) but not F24 (which I accidentally did not reenable USE_OPENGL until just now).
Similar problem in webkitWebViewBaseUnrealize, I'll test a fix later today. And I'm switching F24 back to USE_OPENGL since bug #126122 and bug #150955 will both be fixed in the 2.11.91 update.
It's not so simple, another problem is that in WebCore::PlatformDisplay::createPlatformDisplay, gdk_display_manager_get_default_display returns some non-null display for which neither GDK_IS_X11_DISPLAY nor GDK_IS_WAYLAND_DISPLAY is true, and we wind up creating a PlatformDisplayX11 in the fallback path (we should really have an ASSERT_NOT_REACHED there), so any code that checks the display type can never work. Since I think nobody cares about this configuration, I'd rather just fail the build at the configure stage, rather than investigate more and try to make this work.
(In reply to comment #3) > It's not so simple, another problem is that in > WebCore::PlatformDisplay::createPlatformDisplay, > gdk_display_manager_get_default_display returns some non-null display for > which neither GDK_IS_X11_DISPLAY nor GDK_IS_WAYLAND_DISPLAY is true Well I couldn't explain that, so I thought about it a bit more, and actually it is returning a GdkDisplayWayland. The problem is that our Wayland support depends on OpenGL, and we have it baked into our build system to enforce this. I can see in our build logs: -- Disabling ENABLE_3D_TRANSFORMS since ENABLE_OPENGL is disabled. -- Disabling ENABLE_WAYLAND_TARGET since ENABLE_OPENGL is disabled. -- Disabling ENABLE_WEBGL since ENABLE_OPENGL is disabled. -- Disabling USE_REDIRECTED_XCOMPOSITE_WINDOW since ENABLE_OPENGL is disabled. -- Enabled features: -- ENABLE_ACCELERATED_2D_CANVAS ............

Nothing to change here, I think.
