[Closed] gw drawing methods are flicking?

Hi guys!

I’ve got another problem absolutely not related to my precedent custom attributes worries. Is it possible to display things with gw.text, etc. methods without having a disturbing flicking?
exemple:

function onScreenTags =
(
	gw.setTransform(Matrix3 1)
	for i in objects do (
		local pos = gw.wTransPoint i.center
		gw.wtext pos i.name color:white
	)
	gw.enlargeUpdateRect #whole
	gw.updateScreen()
)
registerRedrawViewsCallback onScreenTags

thanks!
Paul.
