Synaptics stops working after some time

I’m running the synaptics driver on X11 using i3wm. Tapping the touchpad and using two fingers to scroll will work just fine after starting the X server.

A few minutes later, at some point the trackpad will simply stop recognizing the second finger when attempting to scroll. Tapping also becomes impossible and I have to press the clickpad to send a click. I’m still able to use the touchpad normally, synclient shows the correct settings and the mouse acceleration stays the same (compared to switching to libinput).

There is no error message present in dmesg. The synaptics driver also stopped starting recently when I just had the configuration file in /usr/share/X11/xorg.conf.d/. I only got it to work by copying the configuration file to /etc/X11/xorg.conf.d/ as well.

I’m running on Fedora 33, my synaptics configuration can be found here: Section "InputClass" Identifier "touchpad catchall" Driver "sy -
The output of synclient: Parameter settings: LeftEdge = 1574 RightEdge -

Has anybody got an idea what could be causing this?
