Mouse cursor jumps to top-left corner with libinput "custom" profile

After doing a recent system upgrade, my mouse cursor jumps to the top-left corner if I fire a mouse event (click or release) while the cursor is in motion. A typical motion this resembles is dragging. If I'm careful to only click before a motion started and after it stopped, no jumping occurs. This only happens with libinput's "custom" acceleration profile, which I've been using with success until now. The "flat" and "adaptive" profiles do not show this behavior.

I'm on Xfce. I can enable the "custom" profile through the following command (0 0 1 toggles "flat" (0) "adaptive" (0) "custom" (1) respectively):

xinput set-prop "My Mouse" "libinput Accel Profile Enabled" 0 0 1

libinput was among the updated packages, though I'm not certain it's the culprit:

[ALPM] upgraded libinput (1.28.1-1 -> 1.29.0-1)

Can anyone confirm this on their side?

Re: Mouse cursor jumps to top-left corner with libinput "custom" profile

I was fight against same left-corner mouse jumps two years ago, when i was using custom "Coordinate Transformation Matrix". Now Accel Custom Profile is bugged too. I have same problem since 2025-08-18 when i upgraded linux from 6.15.9.arch1-1 -> 6.16.1.arch1-1 and libinput from 1.28.1-1 -> 1.29.0-1. As an emergency temporary solution I use now Custom Profile disabled and mouse Accel Speed slowdown to -0.9 but im not happy with this setup.

        libinput Accel Speed (288):     -0.900000
        libinput Accel Speed Default (289):     0.000000
        libinput Accel Profiles Available (290):        1, 1, 1
        libinput Accel Profile Enabled (291):   1, 0, 0
        libinput Accel Profile Enabled Default (292):   1, 0, 0
        libinput Accel Custom Fallback Points (293):    <no items>
        libinput Accel Custom Fallback Step (294):      0.000000
        libinput Accel Custom Motion Points (295):      0.000000, 2.000000, 8.000000, 32.000000
        libinput Accel Custom Motion Step (296):        4.000000
        libinput Accel Custom Scroll Points (297):      <no items>
        libinput Accel Custom Scroll Step (298):        0.000000
