The mouse cursor jumps here and there on the screen all the time, unless I do extremely slow mouse movements. I dont find any way to make it work good. Any suggestions?

Oh forgot to mention, trying to play Simon the sorcerer 2, the first game works :)

Hi,

This apparently is a problem in old version of SCUMMVM that happen in Windows 10.

The solution is to use "Kirben updates"

If you know your way around SCUMMVM you can probably do this yourself.

A more permanent solution would be to contact GOG and make sure they use the correct version in their installers. (if no one does it I'll open the ticket myself when I have more time).
