            Bug ID: 192523
           Summary: [WPE][GTK] Accelerated compositing mode is in poor
                    state on trunk
           Product: WebKit
           Version: WebKit Nightly Build
          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

Unfortunately accelerated compositing mode has suffered some regressions between 2.22 (where I believe it was working *almost* well enough) and 2.23.1. I've made the executive decision to disable AC mode in Epiphany git master since this fixes several issues, including annoying issues with GitLab that were making development difficult. I'll leave it enabled in 3.30 for a while longer because 3.30 branch users are expected to use 2.22, but when we get closer to 2.24 release I'll go back and disable it there too.

Here are the issues:

 * Bug #178387 (an old bug, but I do not remember hitting it in 2.22)
 * Bug #182276 (seems like a recent regression)
 * Bug #192230 (seems like a recent regression)
 * Bug #192522 (not a regression from 2.22, but a blocker for Epiphany regardless)

I'm also tracking this as https://gitlab.gnome.org/GNOME/epiphany/issues/595.
