Title:
Mouse cursor sometimes can't pass the invisible border on the right
side of the screen
Status in QEMU:
Expired
Bug description:
I'm using qemu 2.11 on Gentoo Linux, with configured GPU passthrough (Radeon
RX580) to the guest Windows 10.
This configuration is alive for last 4 years, this time I changed a lot qemu,
linux kernel and windows versions, changed GPU and always all was working as
expected. I always used standard PS/2 mouse emulation and that was enough for
me.
Now, I bought two new monitors, instead of old one, and setup them as
one logical monitor, using technology called Eyefinity - it's a part
of standard Radeon software. Now Windows thinks, that I have one
monitor with resolution 2160x1920 (I bought Dell monitors with a thin
borders and use them in portrait mode).
Windows uses it without any problems, but mouse become crazy - sometimes (~3
times from each 5) I can't move cursor to the right border of the screen, it
looks like the invisible vertical border. I spent really huge amount of time to
understand, which component is the root of problem and found, that it's really
a mouse. I tried all possible variants (standard, tablet, virtio-mouse-pci,
virtio-tablet-pci), and found, that in both mouse variants bug is reproducing,
and in both tablet variants - cursor stuck near all real borders and corners,
so it's not a variant too.
The only working variant becomes passing real USB port to my VM and insert
second mouse to this port. So, now it's working, but I have two mice on my
working place, which doesn't seems very useful.
Here is my command line:
QEMU_AUDIO_DRV=pa QEMU_PA_SAMPLES=4096 qemu-system-x86_64 -enable-kvm -M q35
-m 12168 -cpu host,kvm=off -smp 4,sockets=1,cores=4 \

secondary-vga \

\
-device virtio-scsi-pci,id=scsi \
-drive
file=/dev/sdb,id=disk,format=raw,if=none,discard=on,cache=none,aio=native,detect-zeroes=unmap
-device scsi-hd,drive=disk,id=scsi0 \
-device ich9-intel-hda,bus=pcie.0,addr=1b.0,id=sound0 -device
hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 \
-usb -usbdevice host:046d:c52b
All in all, I checked on Windows 7 and Windows 10, and on qemu 2.10
and 2.11 - bug is always reproducible.
