The GUICtrlSetPos() function redraws each draw when moving a graphic

[anonymous]

The GUICtrlSetPos() function redraws each drawn line,etc. when moving a graphic, rather than just moving the final resulting graphic, this causes the function to take increasingly long time to execute for graphics which needs updating.

example code to simulate the problem:

; Script to simulate a bug in Autoit.
#include <GUIConstantsEx.au3>

AdlibEnable("GUIUpdate",20)

GUICreate("THIS IS A TEST",400,400)
GUICtrlCreateGraphic(10,10,380,380)
GUICtrlSetBkColor(-1,0xffffff)
GUICtrlSetColor(-1,0)
Global $box=GUICtrlCreateGraphic(20,20,20,20)
GUISetState(@SW_SHOW)
Sleep(3000)



While 1
	If GUIGetMsg()=$GUI_EVENT_CLOSE Then ExitLoop
WEnd

GUIDelete()

Func GUIUpdate()
	AdlibDisable()
	GUICtrlSetGraphic($box,$GUI_GR_PENSIZE,2)
	GUICtrlSetGraphic($box, $GUI_GR_COLOR,0,0xc0c0ff)
	GUICtrlSetGraphic($box,$GUI_GR_RECT,1,1,18,18)
	GUICtrlSetGraphic($box,$GUI_GR_PENSIZE,2)
	GUICtrlSetGraphic($box,$GUI_GR_COLOR,0xff0000,0x00ffff)
	GUICtrlSetGraphic($box,$GUI_GR_RECT,1,1,18,18)
	Local $time=TimerInit()
	GUICtrlSetPos($box,Random(10,360,1),Random(10,360,1))
	$time=TimerDiff($time)
	ToolTip("TimeTaken: "&$time)
	AdlibEnable("GUIUpdate",20)
EndFunc

I am having this problem and can't continue with my project as the project requires constant updating and moving of a number of graphics, hence, taking up all the CPU, gradually slowing down the graphics and finally, stopping.

You are creating too many drawing as you always add.
Just recreate the drawing in your adlib.
