Flickering screen at the edges

Code:
mob
    player
        icon = 'player.dmi'
    Login()
        ..()
        winset(src, "default", "is-maximized = true")
        client.adjust_tiles()
        world << "[src.name] logged in!"

client
    perspective = EDGE_PERSPECTIVE
    proc
        adjust_tiles()
            var
                size1 = winget(src, "map1", "size")
                width = text2num(size1)
                height = text2num(copytext(size1, findtext(size1, "x") + 1))
                xxx = round(width/world.icon_size)
                yyy = round(height/world.icon_size)
            view = "[xxx]x[yyy]"


Problem description: I use the above code in an effort to 1) make the window of the player full (I use a custom window) 2) After that, adjust the tiles horizontally and vertically so that the maximum number of tiles are placed on screen (with adjust_tiles proc of client). This causes the screen to flicker though at the edges of the screen

If I move the character near the middle, it stop flickering. It also stop flickering completely even in the edges if I remove the edge_perspective from the client but I need that. What could be wrong? Thx

(Proven Redundant)

Well, there's a major problem here: you're not properly grabbing the width of the map.

var
 size = winget(src,"map1","size")
 x = findtext(size,"x")
 width = text2num(copytext(size,1,x))
 height = text2num(copytext(size,x+1))
view = "[round(width/world.icon_size)]x[round((height/world.icon_size)]"

Actually, Konlet, he is.

var/val = "41x13"
text2num(val) //returns 41
text2num(copytext(val,findtext(val,"x")+1)) //returns 13


The first copytext is unnecessary because text2num automatically quits when a non-numeric character is found in the sequence.


Just at a glance, though, OP, this looks like a bug.

I didn't know, that's interesting.

This could be an issue with the map file, in the case that your view is trying to display more tiles than the max x and y hold.

Example: If your view is "10x10" but your map is 9x9, issues could arise.

Edited: If I make the map much bigger this stops. If I try to display however it's exact size on view, 10x10 map and "10x10" view this still occurs...

Uh... I can't duplicate that problem. Mine works just fine if the view is larger than the map.

^Give that a download. If it works on your machine, the problem isn't likely a bug, but rather something else in your project causing trouble.

Alright, so this sounds like a machine-specific bug. Something is going on with your specific hardware/software configuration that's causing this issue.

What version of BYOND are you using, out of curiosity?

Actually, my BYOND version is out of date. Lemme check if this happens for me on 1319.
