#65546: Emacs: strange behavior of menu bar (and tool bar)
-----------------------+--------------------
 Reporter:  monte-lin  |      Owner:  (none)
     Type:  defect     |     Status:  new
 Priority:  Normal     |  Milestone:
Component:  ports      |    Version:  2.7.2
 Keywords:             |       Port:  emacs
-----------------------+--------------------
 I installed emacs with the cmd: "port install emacs +gtk"
 Everything seemed fine, and I got "emacs @28.1_1+gtk+nativecomp+x11"

 When run, its frame displayed as expected; both the menu bar and tool bar
 are of light background with black text.
 Immediately after I move the mouse pointer, both bars changed to be in
 black background with gray text on the menu bar (and all levels of menus)
 Even stranger, when we load a large file (such as Emacs manual) that spans
 several pages and then scroll down and up, the menu bar will chang to
 light background with black text ; and change back to dark mode
 immediately after you move the mouse pointer.

 There is no such issue when it's run remotely through remote X.
