            Bug ID: 155492
           Summary: [GTK] Empty window when AC is enabled but OpenGL is
                    not working
    Classification: Unclassified
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org

If the GL configuration is broken for some reason, then any WebKitGTK+ window will be empty if AC is enabled.

This is my the test case:

I use the nvidia propietary drivers, so by setting the path to the mesa ones I mess with my GL setup

$ export LD_LIBRARY_PATH=/usr/lib/mesa-diverted/x86_64-linux-gnu

$ glxinfo 
name of display: :0.0
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
X Error of failed request:  GLXBadContext
  Major opcode of failed request:  155 (GLX)
  Minor opcode of failed request:  6 (X_GLXIsDirect)
  Serial number of failed request:  54
  Current serial number in output stream:  53


Now if i run MiniBrowser I always get an empty window for any site that enables AC (even google.com)

No crash however. I don't get a coredump and the webprocess don't crashes.


If I manually opt to disable AC by doing

export WEBKIT_DISABLE_COMPOSITING_MODE=1

Then all works (no fancy animations, but it just works fine)
