I did exactly the same as you described once more and Lyx disappeared.
Using Qt version 5.14.1 in /usr/lib.

If you go right with arrow, this opens right to the active menu. If you go to the left from menu item that hasn't sub menu (let's say, Navigate – Next Note), Lyx is not crashing and that opens next to the left menu.

Can you give more detailed instructions? Here's what I did (using
English GUI):

1. Alt-N, to open the Navigate menu

2. Bookmarks is highlighted, so hit right arrow to open that menu.

3. Hit right arrow again. This takes me to the Document menu.

What version of Qt is installed on your machine?


I think, I narrowed the cause. I'm working in Wayland (Sway). There is no crash when I'm launching Lyx with xwayland (as "QT_QPA_PLATFORM=xcb lyx") and hitting right when I am in the Bookmarks sub-menu takes me to the Document menu. But Lyx in Wayland crashes when I do the same.
I just receive your mail. Yes, it's Wayland.

 One more small thing Alt-I (to open Insert menu) isn't working when you press it first after launching program while other menus all are working. After launching some other menu by Alt Alt-I is working. That is in Wayland and X11.
