Public bug reported:
Recently we upgraded to a distribution that bundled QEMU 4.2.0. We were
previously running on QEMU 3.0.0. When booting Windows 10 VMs on
x86_64, users experienced slow, monochrome graphics and the resolution
was restricted to 640x480. Reverting to the prior vgabios-cirrus.bin
from the prior source tarball remediated the issue.
An example QEMU command line is below, if needed:
/bin/qemu-system-x86_64 -vnc 0.0.0.0:100 -device cirrus-vga,id=video0,bus=pci.0,addr=0x2 -machine pc-i440fx-4.2,accel=kvm,usb=off,dump-guest-core=off -cpu qemu64 -m 2048 -overcommit mem-lock=off -smp 1,sockets=1,cores=1,threads=1 -no-user-config -nodefaults -hda test.raw &

This seems to be the following SeaBIOS bug:

Ah, great catch! Yes, that does appear to be the issue+fix. Is QEMU
planning on integrating the next release of SeaBIOS or fixing this as a
one-off for now?

Yes, the maintainer will likely get the submodule updated before the
next release.

This issue is still marked as unresolved almost 6 months later. Has the
submodule been updated and merged into QEMU yet?

The patch mentioned by Philippe ("vga: fix cirrus bios") has been included into QEMU via this commit here:
https://git.qemu.org/?p=qemu.git;a=commitdiff;h=de15df5ead400b7c3d0cf2
... which has been released as part of QEMU v5.1 already. Thus this issue should be fixed now.
