Hi export,

I am porting Froyo to an mips based platform now, to reduce the memory requirement, we decided to change the surfaceflinger double buffer mechanism to single buffer, everything seems fine except that when we hold the mouse and drag it through the screen in some application, the garbage will be visible for a short while on the track of mouse movement, and garbage turn out to be the wall paper surface that should be under the application surface.

    My question is what will cause that problem  ?

Thanks
Felix
