Reproducible in FF and Chrome.

Using Debian Bullseye with Xfce.

I've tried more approaches to fix it but evey had some glitch:

• changed 40 to 0 in trackMoveEvents (this causes that when map is thrown it doesn't have always the best speed/direction)
• called trackMoveEvents in mouseup handler - it improved the thing a bit but not at 100%
