    Hello folks
    I am using iMac with intel
    Parallels 18.0.1
    I have a guest machine: Archlinux (updated), parallel tools(added)
    I dont know why but I have a graphics problem. The xf86 drivers I have installed are:
    • extra/libxxf86vm 1.1.5-1 [installed]
    • extra/xf86-input-libinput 1.2.1-1 (xorg-drivers) [installed]
    • extra/xf86-video-vesa 2.5.0-3 (xorg-drivers xorg) [installed]
    Please check the image below:

    I am in the same boat as yourself. I believe it is attributed to that XSAVEC issue (a change has been introduced in kernels 5.19+, see This results in many applications crashing -- the most noticeable on Arch are Chromium and anything that uses its rendering capabilities under the hood, e.g. any Electron app. I am currently surviving by using Firefox with hardware acceleration disabled.

    I think you can combat the majority of the graphics issues if you revert back to the prl graphics drivers from the recently introduced virtio-gpu, but I think the proper fix should come from Parallels by addressing XSAVEC issue (which all the competitor fixed like an year ago) and also reviewing how their virtio-gpu is exposing its interfaces (there are some issues with the selected IDs for that device, so some libraries cannot recognise it as a virtio-gpu:

    [galaxy@archlinux ~]$ lspci | grep -i virtio
    00:05.0 Ethernet controller: Red Hat, Inc. Virtio network device
    00:0e.0 RAM memory: Red Hat, Inc. Virtio memory balloon
    01:00.0 VGA compatible controller: Red Hat, Inc. Virtio GPU (rev 01)
    [galaxy@archlinux ~]$ cat /sys/devices/pci0000\:00/0000\:00\:01.0/vendor
    [galaxy@archlinux ~]$ cat /sys/devices/pci0000\:00/0000\:00\:01.0/device
    [galaxy@archlinux ~]$
    The device, IMO, is supposed to be 0x1050 for the device if it tries to mimic Red Hat's virtio-gpu, but I am not that knowledgeable in the virtio space, so I may be wrong here.
