Forgot to mention, the crash is a segfault.
If there is more information needed, I am happy to provide it.
** Description changed:
Hello,
I am using an uptodate Arch Linux 64bit with qemu version 4.2.0, but the
problem was also present in older versions. The problem occurs with Linux 5.4
and 4.19.
The problem also occurs with Debian as guest. I am running sway.
If I provide -vga std, then qemu works fine until I use the qemu window to
switch to the vfio-pci device. There are no problems under X11/xwayland at all.
