Dear community,
We are making a x-window appllication software. ( BSP Rev is 3.14.28 )
When the application update a screen ,we get flicker.
Especially, using a XRandR for screen rotation , a screen is distracted step-like.
How can I avoid the flicker ?
Could you advise us a workaround ?
I think that this phenomenon is related with two bugs as follows.
Is it correct ?
1."xrand rotation is not accelerated by GPU"
Reduced graphic performance with rotated screen (imx6, sabresd)
2."Tearing ,it is described on i.MX 6 Graphics User’s Guide"
*****************************************************
I captured the SABRESD display, please refer to an attached file.
The reproduction methods of the phenomenon are as follows.
$ flickering.sh &
$ export DISPLAY=:0.0
$ xrandr
$ xrandr -o right
