Hi.

Moving really slowly (like 0.3cm/sec) results in the cursor not moving at all.

• Only occurs when moving downwards or rightwards.
• Does not occur when moving upwards or leftwards.
• Occurs for the apple touchpad and some mouse.
• Does not occur under libinput on X11 or weston.

Note: on the touchpad I start from the middle to avoid any of the palm detection (which triggers if you start from top left or top right)

I confirmed I am using libinput on X using

arch:~$ grep -e "Using input driver " ~/.local/share/xorg/Xorg.0.log
[ 25022.988] (II) Using input driver 'libinput' for 'USB Optical Mouse'
[ 25023.031] (II) Using input driver 'libinput' for 'bcm5974'

My sway settings:

input "1133:49242:Logitech_USB_Optical" {
    accel_profile flat
}

input "7247:3:SIGMACHIP_Usb_Mou"{
    accel_profile flat
}

input "5426:67:Razer_Razer_DeathAdder_Chr" {
    accel_profile flat
}

input "1452:594:Apple_Inc._Apple_Internal_Keyboard_\/_Trac" {
    accel_profile flat
    tap enabled
    scroll_method two_finger
    dwt enabled
    natural_scroll enabled
}

input "1452:594:bcm" {
    accel_profile flat
    tap enabled
    scroll_method two_finger
    dwt enabled
    natural_scroll enabled
}

My X11 settings:

Section "InputClass"
    Identifier "libinput touchpad catchall"
    MatchIsTouchpad "on"
    MatchDevicePath "/dev/input/event*"
    Driver "libinput"

    Option "Tapping" "true"
    Option "NaturalScrolling" "true"
    Option "DisableWhileTyping" "true"
    Option "ScrollMethod" "twofinger"

    Option "AccelProfile" "flat"
EndSection

Version info:

arch:~$ pacman -Qi wlc-git
Version         : 0.0.5-1
arch:~$pacman -Qi sway-git
Version         : r1863.49afdb4-1
arch:~$ sway -v
sway version 0.9-38-g49afdb4 (2016-08-10, branch "master")

Thanks.

@psgarsenal no https://github.com/Cloudef/wlc/issues/166#issuecomment-237883598 does not solve the issue. I believe the profile is already flat, and there is something else screwing with the cursor when going rightwards and downwards.

Do you have this issue with weston?

No. Weston works perfectly (with both mouse and touchpad) in all directions.

Ok so I did some testing, and it turns out that "accel_profile flat" in sway does not solve my issue, and that it does not appear in weston, so this issue and mine (#166) are the same

Basically, to sum up both issues, there is a problem that causes slow movements to not be detected in certain directions, depending on the mouse. I don't know about the apple's trackpad, but it seems that our problem is still linked with hi-dpi mice

@psgarsenal your linked issue seems to have different symptoms, are you now exhibiting my symptoms also?

Symptoms were the same explained differently, i cannot move my mouse slowly, in the down-right direction, I just thought moving it in circle would show it better on video. It must be something with the hardware acting in a different way than "traditional mice", since, as you can see in my issue, a 5 buck mouse don't have this problem.

Logitech B100 at 800dpi and Razer Deathadder Chroma at 1200dpi, Sigmachip at 800dpi

• all show the issue with no configuration applied
• but do not show the issue with accel_profile flat

The Logitech I have at work shows the issue, but i'll check this again when I next go in.

Apple touchpad

• does show the issue with accel_profile flat
• I confirmed the settings are being applied as natural_scroll does apply
• it's so bad that sway is basically unusable
• works perfectly in weston and x11

Any updates on this? The issue persists with the actual master using Apple Touchpad.
