Since installation via upgrade of Kubuntu from 22.10 to 23.04, laptop touchpad input been very laggy. Mouse input by USB has no problem. Hardware is an 81V5 Lenovo V155-15API running Kubuntu 23.04 kernel 6.2.0-20-generic
Problem apparent also when running either Ubuntu (Gnome) 23.04 or Kubuntu 23.04 from USB flash drive. No issue when running 22.10, new owner so untested with 22.04 etc.
