Reported both as a Debian kernel issue: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1029584
(since I thought for a while that it was that) And as a libinput issue: https://gitlab.freedesktop.org/libinput/libinput/-/issues/852 I dunno what the proper fix would be, or where, but I am sure it can be figured out. Posting here so the reports are discoverable for people that have the same issue. Best, Tobias
