I am running RPi 3B with Waveshare 5" (B) screen, piCorePlayer 4.

I can calibrate the screen properly with ts_calibrate and touch works correctly with ts_test, but then touch is away from touching point in Jivelite.
I use Grid Skin 800x480 to match the screen, but the issue seems to be similar also with other skins.

Any ideas what can be wrong?
