Sticky trackpad

Since I have updated to 11.4, the trackpad became sticky and less responsive. I have tried to play with the configuration (Personal Settings > Input Devices) without success. It is not the speed or the acceleration, it is as if the trackpad is disabled after not using it for a while. Only after moving my finger on it for a while it becomes enabled again and it works normally.

I heard from many people with very sensitive trackpads that they hate when they move it by mistake. The described behavior will be for them a feature, but for me is a bug. Can I revert to the 11.3 way?

I have a Tecra A7 and the Touchpad information says SynPS/2 Synaptics TouchPad
