Yes I can definitely see this to be an issue... sorry I didn't acknowledge this Wally4000. My application does store alot of images in memory for fast performance... looks like I'll have to cut down on the memory usage and perhaps create a caching system of some sort for the memory images in questio...

Insert_witty_name: Well, how is your display list declared, how are you allocating your vertices in each drawing function? The line of code (a call to another function) that makes the difference whether this crash happens or not is not even executed... so I don't think it has anything to do with thi...

Draw buffer and display buffer
When attempting to draw parts on the screen rather than clearing the whole screen and re drawing all parts I am currently faced with a problem: all images (except the first screen sized background image) disappear, and then reappear once the I draw the next object.
