      I wish they would better document and address QEMU's user-emulation mode. This mode allows you to run a binary from another architecture without the overhead emulating a whole guest operating system. It merely emulates the program binary and translates it's syscalls to the host architecture's operating system.

      While this is FAR more performant, it continues to be impossible to find any official documentation on it. I would like to be able to utilize host graphics acceleration in this configuration, which likely has issues translating syscall datastructures, but this is impossible to sort out without documentation on how qemu handles syscalls in this mode. The only documentation I can find is on passing through a GPU device to a full virtual machine, and even that if from folks like Debian, not official QEMU documentation.

      There may well be a way to make it work using various indirect or remote rendering technologies over loopback, but without documentation it's just stumbling around in the dark.
