Disabling compositing leads to black line around some menus (see the screenshots)

1) start with default xfce4 config (compositing on)
2) disable compositing - unselect Settings/Window Manager Tweaks/Enable display compositing
3) there is an ugly ~10px wide black stripe around Applications menu and panel right mouse button menu

Strangely, the line (stripe) is only around top level applications menu, not around
submenus. The submenus lacks the proper 1px thick border, though. For panel rmb menu,
the thick black line is both around context menu and its submenu.

Upon restarting XFCE, the black line goes away.

Could this have been bug 14577?
Comment 8 Adam Purkrt 2020-01-11 23:48:21 CET
I would not say so. The bug is still there. I just retested and it triggers after the following set of steps

1. Turn on display compositing (Settings/Window Manager Tweaks/Compositor/check Enable display compositing)
2. Log out of Xfce - I use startx to start the X server, so logging out shut downs the X server
3. Start Xfce again - startx in my case (which starts startxfce4 --with-ck-launch)
4. Turn off display compositing (uncheck Enable display compositing)
5. Click on "Applications" menu - the menu will appear with a thick black line around it.

Upon another restart of X, the black line around the menu goes away. So this is admittedly a rather minor bug (you encounter it only during the X session which started with enabled display compositing and during which the compositing was switched off).

Panel menu with black line around it.

Marking this attachment as obsolete, since the panel menus are now always ok. I am unable to trigger the bug for them. But the Applications menu still can have the thick black line around, under the conditions described above.
