I have a custom board using u599 and touchgfx, my LCD size is 640*480.I noticed there is a "nemagfx_stencil_buffer_mem" in my RAM,It takes 305K memory,It's really a lot memory ,because I only have 30K left.But on the other board,lcd size is 480*480,"nemagfx_stencil_buffer_mem" is not there.I wonder what use is this buffer,and why it came out.
