SIGSEGV when navigating menus in libreoffice (and zim)

[fdlamotte]

I've had a strange behaviour last month with sway (currently using sway version 1.4-5d13f647 (May 25 2020, branch 'master'))

Once in the menu of some applications (libreoffice, zim), if I leave the window without closing the menu (leaving it to the titlebar for instance) sway crashes. Don't know if it is related to sway or wlroots, but since I experience this in sway I report it here.

I managed to get some time to grab a backtrace, here it is :
