Hi all

I made an application to be run on a touchscreen monitor.
It consists on some buttons with a label placed over them

what if strange is that if I place them over an Image object and want to swap the image.picture i have a annoying flickering of the labels.
They flashed as the background picture changes.

I tryed with lockscreen but without success.

The buttons are placed over the screen object just like the image object.
What can it be ?

thanks
Alessio
