Thank you, Jukka, for your information! After I read your comment, I contacted the Acer-Support and described the problem. Also I told them the procedure to solve the problem, how you explained. The support asked me to send them my computer for repairs. Today I got the computer back with the note, that they changed the touchpad from another manufacturer and upgraded the BIOS.
If the problem will come back, I will write a comment in this bug-report again. But untill now it works fine, and I hope too, that it will keep going on this way!

It seems to me that there are also some events (like clicks) that get fired. This issue can be worked around by disabling and enabling the touchpad (pressing Fn+F7 twice) but it will reappear after a certain amount of time.
