[Qgis-developer] Possible memory leak in rendering code

[Matthias Kuhn]

Hi Alex,

I found in the past particularly two things making the rendering more 
stable:
* Disable Render Cache
* Enable Backbuffer (only availale in X11/Linux)

Can you check if one of these two changes in the options fix this issue?
(Restart after changing)

Cheers,
Matthias
