Can you please share QEMU command line? Any maybe your CPU model.

You can also install driver manually (tutorial), but I'm afraid, there is something wrong in your installation or with QEMU settings.

The problem is the following, by default Windows 98 add VGA device without detect the real VGA device, after https://computernewb.com/wiki/Install_QEMU_Tablet_Driver_on_Windows_98 add new VGA device and enter in conflict due to same IRQ range
