No.It was for X window backend on x86 linux. DirectFB is running on arm-linux platform where i don't have valgrind support. > As I'm sure you > know, apps never (almost never) shrink.

When i run this on windows there is increase in memory usage as seen in task manager but its not steady. After few mins if the application is still running without minimizing increase in memory was observed. On x86 linux with Xwindow backend i didnt see any increase in memory even after running the program for 5 mins as seen using system monitor. On DirectFB backend on Davinci MVL, i see steady increase in memory usage using 'top'. It starts from 4.2% and goes up steadily and after 2-3 min of running this program, memory usage went up to 86% and program slowed down and eventually crashed saying out of memory. I have 256MB ram on Davinci. On DirectFB backend i used DirectFB 1.1.1 with GTK+ 2.12.2. Is there any issues with using these versions since i am able to observe huge leaks on DirectFB backend. Is there any possibility of build procedure going wrong somewhere while building it for Davinci? I somehow feel destroy is not happening properly on DirectFB backend! Has anyone run GTK on DirectFB having multiple windows and not observed any leak? > > I don't have a directfb install to test it on, sadly. Thanks for your help.
