[Qt-interest] Screen flicker using -graphicssystem opengl

[Malcolm Sequeira]

Hi,

I am developing a software, that has a lot of animations.
For this I use a QGraphicsScene to display all the QGraphicsItems.
Most of the animations are only moving the QGraphicsItems around the screen.

This software is deployed on an embeded linux system.
Using native rendering the animations do not appear as smooth, as
compared to using '-graphicssystem opengl.'

However the problem with the using '-graphicssystem opengl' is, it
causes the screen to flicker a lot.

Is there a possible solution to avoid the flickering.
Or is there anyway to specify double buffering (if that would help..)

Thank you.
Regards
Malcolm.
