Wayland on FreeBSD

[Grzegorz Junka]

I am able to start sway, which in turn seems to be starting Xwayland. 
But I don't seem to be able to open any graphical applications?

This is what's running when grepping by sway/wayland:
g          2706    0.0  0.1  144304  68280 v0  I    23:55 0:01.07

swaybar -b bar-0

Firefox briefly opens a window stating that there was a problem then 
dumps core.

Kwrite displays this then nothing happens:

% kwrite
sonnet.core: No language dictionaries for the language: "C"
sonnet.core: No language dictionaries for the language: "C"

qt.qpa.xcb: QXcbConnection: XCB error: 11 (BadAlloc), sequence: 476, 
resource id: 908, major code: 53 (CreatePixmap), minor code: 0

urxvt doesn't print anything and doesn't open anything, just doesn't 
return to the shell

The mouse seems to be working fine in Sway, I don't know about the keyboard.

Anyone is able to see what I am doing wrong?
