gtk-play example assumes that GTK's GL support always works if it is compiled in and first tries to use gtkglsink element which leads to problems if there are errors while instantiating GL context at a much later stage. This failure isn't detected and there is no fallback at this point. gtkglsink works on wayland though using poky defaults with gtk+3 since the gdk backend does support egl with wayland but it doesn't with x11. Disable the gtk plugin to ensure gtk-play just moves on when gtkglsink isn't present. This was the default when gtk was part of -plugins-bad before upgrade to 1.14.0.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
