           Summary: Wrong active context when destroying GL objects
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit Gtk
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: itoral at igalia.com


When we have multiple webviews, each with its own GL context, it is possible that destroying a view (for example closing a tab in the browser) triggers destruction of the underlying LayerTreeHost with the wrong active GL context. We should make sure that we set the right context as active before destroying GL objects in LayerTreeHostGtk::invalidate.

I'll attach patch shortly.
