weston-terminal renders as a black square, other weston-* tools are fine

Using Weston 12.0.2, other weston-* clients work such as weston-flower, weston-editor, weston-simple-egl, weston-simple-shm, etc. However the weston-terminal renders as a solid black square. The terminal itself functions fine. Commands entered into the terminal run. The mouse cursor also changes when moving over the text area of the terminal vs. where the menu bar presumably is. The window can be resized, but it doesn't cause it to render properly. A right click menu also appears to exist but not be rendered, as blindly right-clicking occasionally spawns a second terminal window. Other terminal programs such as xfce4-terminal work.

The weston backend is weston-drm. The GPU is intel integrated graphics on an i7-6600U. The kernel is 6.6.7-arch1-1. The weston.ini is minimal, there's no [terminal] section. I tried launching weston-terminal --font="..." with several monospace fonts such as "DejaVu Sans Mon" and "Noto Sans Mono" without any improvement.

$ cat /sys/class/drm/card1/device/vendor 
0x8086
$ cat /sys/class/drm/card1/device/device 
0x1916
