I believe so, CentOS 7 still has menu issues.

& I did see other oddness -  but still definitely better with inhibit-double-buffering

loading with init.el that only contains:

modify-frame-parameters nil '((inhibit-double-buffering . t)))

emacs -q -l ./init.el

CentOS7, gtk: 2.24.31,  gtk3: 3.22.10
| emacs      | VcXsrv                           |
| 25.3  gtk2 | ok                               |
| 25.3  gtk3 | ok, no emacs logo, menus no show |
| 26.1  gtk2 | ok                               |
| 26.1  gtk3 | ok, no emacs logo, menus no show |

OpenSUSE Leap 42.3 , gtk2: 2.24.31,  gtk3: 3.22.10
| emacs      | VcXsrv                    |
| 25.3  gtk2 | ok                        |
| 25.3  gtk3 | ok, but no emacs logo (1) |
| 26.1  gtk2 | ok                        |
| 26.1  gtk3 | ok, but no emacs logo (1) |


OpenSUSE Tumbleweed, gtk2: 2.24.32,  gtk3: 3.22.29
| emacs      | VcXsrv                    |
| 25.3  gtk2 | ok                        |
| 25.3  gtk3 | ok, but no emacs logo (2) |
| 26.1  gtk2 | ok                        |
| 26.1  gtk3 | ok, but no emacs logo (2) |

(1)  "About GNU" launches external browser when in ssh
remote session. But "M-x eww gnu.org" will display in eww mode. 
Additionally, local emacs session uses Eww mode for the about pages, and
displays emacs logo.

(2) "About GNU" launches non-emacs text editor of .html when in ssh
remote session. But "M-x eww gnu.org" will display in eww mode. 
Additionally, local emacs session does use Eww mode for About GNU.
but also opens the .html into non-emacs text editor (gedit), and does not display emacs logo at startup.

And according to the table you show, those menu problems are resolved
in a later version of GTK+, is that right?
