However, starting the Redox GUI (orbital) brings up the graphical interface and then starts using 100% CPU. I'd guess it's related to mouse detection and handling. The OS image is fully usable on x86. https://www.dropbox.com/s/u6v2k9wzcuiycfo/redox-disk.img.xz?dl=0 Which QEMU version have you been using here? Can you still reproduce the problem with the latest upstream version of QEMU? [Expired for QEMU because there has been no activity for 60 days.]
