buggy mouse in qemu

[RetroGamerCX]

hi, i'm new here, and today i virtualized mac os x 10.0 in qemu. however, when I moved the mouse it started to move to the left and click at the same time. here is the configuration of the qemu that I put:

qemu-system-ppc.exe -L pc-bios -boot c -M mac99 -cpu G3 -m 2048 ^
-prom-env "auto-boot? = true" -prom-env "boot-args = -v" -prom-env "vga-ndrv? = true" ^
-drive file = osx.img, format = raw, media = disk ^
-sdl ^
-netdev user, id = network01 -device sungem, netdev = network01 ^
-usb ^
-device usb-mouse ^
-device VGA, edid = on

i'm using the 19-8-2020 version of qemu, which is the most recent
here's the host configuration:
ram: 16gb ddr4
hd: 1tb
motherboard: asrock a320m-hd
Processor: amd a6-9500 @ 3.50 ghz
operating system: windows 10 pro 64-bit

Hi,

I can't reproduce that. Does it happen when running any particular program?
You might want to consider running without -cpu G3.

There is no need to add an usb controller with -usb. Simply adding -device usb-mouse is sufficient.

Is the mouse still buggy when you run without -usb -device usb-mouse?

Best,
