nothing is going to change here until we have object auto-buffering (and partial updates of auto-buffered content). this has been explained before as to how the compositor canvas works - it is NOT like other compositors. our compositor canvas has everything broken down into primitives. every letter you see in a titlebar or on your shelf is 2 triangles. as opposed to elsewhere where it's one big buffer for the window including titlebar. every little primitive in the shelf is groken down. we're generating 100's and 1000's of triangles per frame. > Hi, > > I have a similar problem (intel graphics).
