6 years ago I'm seeing the same thing on Gnome 3.30 (Arch Linux 4.18.16) with system Cairo version 1.16.0 and xorg-server 1.20.3: R reliably segfaults after opening a second X11 device and trying to move or resize either the first or second plot window:

*** caught segfault ***
address 0xe10000c3, cause 'memory not mapped'This happens 100% of the time for me, at least when I open the two windows in quick succession. It seems less reliable when there's a delay between opening the first and second.
Are there any logs or other debugging steps that would be useful for you to track down the root cause of this?
I'm using a tiling window manager and am consistently observing CairoX11() crash my R process when using multiple instances.
