[meta-freescale] [meta-fsl-arm] Memory leak in graphic application (dora)

[Vincent DEHORS]

Hi, 

I am not using the Intel driver but the Vivante one packaged
by these recipes :

Do you think I can use another version of gpu-viv-bin-mx6q and
xf86-video-imxfb keeping my 3.0.35 kernel ? 

Regards, 

Vincent

I didn't need to add this for the 2.99.910 version of xf86-video-intel
included with 'daisy'.

Is there any known issue with graphic application in old BSP for i.MX6 ?
