Hi yakas, in the current beta there has been some changes to use multiple CPU cores to help speed up the display, maybe you're running into some problem related to that.

You can disable it by a setting in moi.ini - to do that go to Options > General and push the "Edit .ini file" button. Then inside there find the [View] section and inside there find the DisplayThreadLimit= setting and set it to say:

DisplayThreadLimit=1

Does that make any difference?

Also what kind of video card do you have in your machine?
