BTW, we face another problem. We prepare surfaces containing our icons and other images at the start to have them in memory, and then blit them to the primary surface before flipping it. By default stgfb alocates memory only for the primary framebuffer, but not for out-of-screen memory, and as thus, when doing a blit, it does not copy use accelerated blitting, which is a particular penalty when blending is used (software blend is aroudn 30 times slower than software blit, which is around twice slower than accelerated blitting). The theory is that adding more memory to stgfb (using the g_mem argument) allows for putting the extra surfaces in offscreen memory, and thus using accelerated blitting. The problem is that when we add memory to stgfb, then the blitting of the icons fail.
