Since upgrading to ArchiCAD R2+/V2+ (Build 2284) from V1+ (1410) I have noticed a display bug that occurs in the drawing of stairs which are set up using the story sensitive feature and show on one story above. As I go up and down the building (4 Building Stories + 2 Roof Stories and One Garage Story) the stairs sometimes don't draw properly. Some times it draws the stair as it should be on the floor below or above and sometimes one of the two pieces disappears altogether.
What's even stranger is that it occurs seemingly at random but once it occurs it usually is triggered by changing from the same floor (like from floor 3 to 2 but not 1 to 2). What's also interesting is that 6 of the stair towers in the project use the exact same library part yet it happens randomly on only some of the stairs at a time.
Is anybody else experiencing this? To test just go up and down your building from bottom to top to bottom a few times and check to see if the stairs draw correctly on the way.
For reference I use OS X 10.3.3 as my OS. The other display bug was Mac specific maybe this one is also.
