The following call to XQueryBestCursor returns a width and height of 0. XQueryBestCursor(dis, d, 32, 32, &width_return, &height_return); Whereas when not using Mir it returns a width and height of 32. I've attached a simple X11 application that shows the difference. (or it can be seen here https://bitbucket.org/hindlemail/x11testapplication/src/adaba4419fcaec3e9031223b43f0e62f6593a578/main.c?at=default) This difference prevents all mono winforms applications from running.
