"Another hint has been posted by 'rzookol' - according to him, the missing font vera.ttf in the mossys:fonts/_ttf directory is also a reason for a lower performance of the PowerUp version. As a solution, you can rename a copy of the font verase.ttf: "copy sys:morphos/fonts/_ttf/verase.ttf sys:morphos/fonts/_ttf/vera.ttf". Pegasos owners can copy the missing font from their corresponding MorphOS installation."
this is the main reason for the delay when you open a window.
After to have copied the Vera.ttf, all works fine even at 1024x768
