The map Alex used for testing is map08 of rjumpq.wad and the effect can be produced as of r3503 by looking downward over the ledge at the first jump. It was my hope that r3408 would fix this problem but that does not seem to be the case. Upon opening the map in a map editor, I noticed the ceiling height is 32767 throughout the map with the floor height ranging from 0 to 1500. It seems very likely that an integer overflow is to blame for this. This problem appears to be fixed in the persdiv branch. |
Created attachment 404 [details] Moire pattern. Simply run forwards from the start, RJing over the "start wall" if need be. Don't make the first jump though, just look down and start walking towards the edge. Eventually, you will see a huge moire pattern fill your screen. Sean asserts that it is an integer overflow of some sort.
