            Bug ID: 149568
           Summary: [GTK] Crash in
                    WebCore::GLContextGLX::defaultFrameBufferSize
    Classification: Unclassified
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at igalia.com

Full backtrace downstream. Notable:

        msg = 0x55dfb73b3690 "The program 'WebKitWebProcess' received an X Window System error.\nThis probably reflects a bug in the program.\nThe error was 'BadDrawable (invalid Pixmap or Window parameter)'.\n  (Details: serial 581 "...

So the rest of this backtrace is surely irrelevant, but I'll post it anyway....
