  what():  Unexpected WM!
fish: Job 1, 'stuntrally' terminated by signal SIGABRT (Abort)

[cryham]

I have little idea what happened (and what to do), but this is so early that I'd suspect mesa, EGL, or something GL and rendering related in this OS. Maybe @paroj has more ideas.

[paroj]

it is your error though:

stuntrally/source/sdl4ogre/sdlwindowhelper.cpp

Line 52 in e86cb51

throw std::runtime_error("Unexpected WM!");

[cryham]

Oh okay, it's our code, or some old helper.
Hmm right, looks like this code or SDL doesn't know this WM.
Perhaps this could be added but that would require building from sources and/or knowing what wmInfo.subsystem is set there and how to get winHandle from it.
