but I think other displays can have same problem.

As visible it doesn't support pressure event. My ts_uinput_touch daemon supports pressure events but I think this is not really important. More important is that it sends button touch event correctly and Kodi reacts like it should.

But ts_uinput daemon is not sending button touch event correctly. Probably because it doesn't get pressure events from touchscreen?
