I cannot post the full log, as x11docker fails to generate it precisely because the error is related to the path of the cache folder.

Thank you for the bug report!

x11docker adds an error message of cmd.exe to the desired path:

x11docker ERROR: Cache root folder must not contain whitespaces.
  '//wsl$/Debian/home/eine'
CMD.EXE was started with the above path as the current directory.
UNC paths are not supported.  Defaulting to Windows directory.
C:/Users/eine/x11docker/cache

The result should only be C:/Users/eine/x11docker/cache.
I've made a fix in 99eae40, please try out.

It works. The error is still shown, but it is no longer in the path:

$ /mnt/t/runx/runx -- /mnt/t/x11docker/x11docker x11docker/xfce xfce4-terminal

  If this display number is already in use, X server startup  will fail.

x11docker note: Using X server option --hostdisplay

x11docker note: Per default x11docker stores its cache files on drive C:.
  docker setup may not allow to share files from drive C:.
  If startup fails with an 'access denied' error,
  please either allow access to drive C: or specify a custom folder for cache
  storage with option '--cachebasedir D:/some/cache/folder'.
  Same issue can occur with option '--home'.
  Use option '--homebasedir D:/some/home/folder' in that case.

x11docker note: To allow protection against X security leaks,
  please install 'xinit' and one or more of:
    xpra, Xephyr, nxagent, weston+Xwayland, kwin_wayland+Xwayland or Xnest,
  or run a second Xorg server with option --xorg.

x11docker WARNING: Option --hostdisplay allows less security hardening.
  It is recommended to use another X server option like --nxagent or --xephyr.
