Descriptive Problem Summary:
Whenever many large icons are used which are very, VERY large, in relatively close proximity to each other (eg, less than a screens distance away) the resulting map output is horribly buggy looking, and messes with the movement-to-map sync.

Numbered Steps to Reproduce Problem:
Create a few large turfs (greater than 20x20 tiles of whatever world.icon_size you like) and place them very near each other (eg, the top of one turf links onto the bottom of the next), run the game in the default topdown perspective and try to move the player between them.


Code Snippet (if applicable) to Reproduce Problem:
N/A

Expected Results:
The player should walk cleanly between the turfs, with no lag or desync, and no visual artifacts.
Actual Results:
Completely skewed map, with no concept of the player's x/y in relation to dense turfs etc.

I have included a screenshot illustrating the problem in greater detail here: http://upload.majhost.com/gallery/RayJT9/BYOND/ bigicons_bug_report.png

Does the problem occur:
Every time? Or how often?
Every time.
In other games?
N/A
In other user accounts?
N/A
On other computers?
Yes.

When does the problem NOT occur?
Tiled Icon Map.

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked?
N/A

Workarounds:
Chop the map up a whole lot smaller if you're using large icons for it, or go back to tiled icon map and use multi_tiled mobs.
