i3wm running in Arch Linux guest (VirtualBox) stops auto-resizing

I'm trying to get Arch Linux to work on VirtualBox. I've followed the instructions on the [ArchWiki](https://wiki.archlinux.org/index.php/VirtualBox#Installation_steps_for_Arch_Linux_guests) and the OS boots fine (running linux-lts kernel, with virtualbox-guest-dkms Guest Additions installed). After installing i3, I've added the following to ~/.xinitrc: VBoxClient-all exec i3 This appears to work, but does the auto-resizing only once. After that, the Auto-Resize Guest Display menu and Seamless Mode in host VirtualBox menu become disabled. What I found out, is that if I kill the VBoxClient process and re-initiate it, the auto-resize functionality starts to work again, but disables as soon the first resize event occurs. killall VBoxClient /usr/bin/VBoxClient-all Can anyone suggest a solution?
