im not sure if this problem is in the solving becaue there was no feedback from the devs that this problem gets solved. So i decided to make a video to show off the problem:
(video)
nothing was changed in the project (expect for the scene names which get displayed by a valuestring).
I display an object text inside a menu:
nothing special. The fonts for object font are based up on betmap fonts.
In 4.2.5 the text scrolls with the X/Y position configured inside the action.
In 5RC0 it does the same unless it hits the border. This breaks many display object text stuff.
I hope this will get fixed soon =)
