createPlatformWindowSurface fails and returns NO_SURFACE which
aborts the program.
Nvidia doesn't seem to support EGL_BUFFER_SIZE 32 with opengl es,
and it seems like we dont need it anyways?

window state reverting to maximized during unmaximization. This
had two causes: the first was that the window geometry would be
set even before ack_configure, which was fixed by moving setting
the window geometry into NoteBounds, and the second was that
NoteBounds would sometimes resize the window back to its old
dimensions if a commit (or subsurface update) happened between
