Bug ID: 42675
           Summary: [Overwatch] Phantom mouse input / view pulled up to
                    ceiling
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

I am using PlayOnLinux on Ubuntu 16.10 and compiled wine with Overwatch patches
from source, first awesie's then gamax92's.
It seems to run fine but every time I'm given control of the character and not
touching the mouse, the viewpoint is pulled up to the ceiling, as if there is
some phantom mouse input. See https://www.youtube.com/watch?v=UMiKAl1tR4s. If I
then pull the mouse towards me fast enough I can overcome phantom mouse input
and pull the view down. Until I stop moving the mouse and the view is pulled up
again. Moving the mouse left or right works fine.
Things I have tried:
If I change the input settings to inverted, the phantom mouse input pulls the
view to the floor.
My standard mouse is a Roccat Kone XTD. I have tried to change the DPI and
polling rate. I have also tried without the drivers installed or plugging the
mouse into different USB ports. And I have tried replacing it with an old Razer
Diamondback. All had the same result.
I have tried the Wine config options "Automatically capture the mouse in
full-screen windows", "Emulate a virtual desktop" and "mouse warp override
default/enable/disable/force".
Within the wine prefix I have ran Xpadder and XInputTest and neither found any
gamepads or joysticks connected (I have neither).
My keyboard is a standard, non USB keyboard. Apart from my mouse the only other
peripherals are a Logitech webcam and a Sound Blaster Tactic(3D) Alpha headset.
Unplugging them does not make a difference.
My PC is a desktop, not a laptop. Raw mouse input works fine in Natural
Selection 2 natively under linux. My /dev/input consists of
by-id    event0  event10  event12  event14  event16  event2  event4  event6 
event8  mice
by-path  event1  event11  event13  event15  event17  event3  event5  event7 
event9  mouse0
In Overwatch I use Borderless Windowed and alt-tabbing out and back in does not
help. If I use Fullscreen and alt-tab out the 3D view becomes very small in the
top left corner and I can't alt-tab back to it.
Not sure if it is relevant, but I am using a GeForce 460 GTX with the latest
nvidia-378 drivers. Motherboard is a Asus P8Z77-V Pro.
For completeness, this is how I compiled Wine:
cd /home/<user>/Documents/Programming/wine64-build
make clean
make distclean
export CFLAGS="-mtune=native -O3 -pipe -fstack-protector-strong"
export CPPFLAGS="-mtune=native -O3 -pipe -fstack-protector-strong"
../wine-overwatch/configure --enable-win64
--prefix=/home/<user>/.PlayOnLinux/wine/linux-amd64/2.3-overwatch/
make -j4
sudo lxc-start -n my32bitbox
sudo lxc-attach -n my32bitbox
cd /home/<user>/Documents/Programming/wine32-tools
make clean
make distclean
export CFLAGS="-mtune=native -O3 -pipe -fstack-protector-strong"
export CPPFLAGS="-mtune=native -O3 -pipe -fstack-protector-strong"
../wine-overwatch/configure
make -j4
cd ../wine32-build
make clean
make distclean
../wine-overwatch/configure --with-win64=../wine64-build
--with-wine-tools=../wine32-tools
--prefix=/home/<user>/.PlayOnLinux/wine/linux-x86/2.3-overwatch/
make -j4
make install
shutdown -h now
sudo rm -rf /home/<user>/.PlayOnLinux/wine/linux-x86/2.3-overwatch/*
