The alpha patch actually reverts the upstream fix. This part:

The depth is hard-coded to 32, which might not be supported,
and the return value from XMatchVisualInfo() is not checked.
If I run this on Xephyr with display depth set to 8-bit, st actually segfaults.
You can see what display depth/class combinations are supported in the output
of xdpyinfo.
