The other two subcases Hoverjet and uimark also drop ~8%. Is this with or without compositing? If these numbers are with compositing, is there a performance change without? (In reply to comment #2) > Is this with or without compositing? If these numbers are with compositing, > is there a performance change without? This is with compositing. Taiji's FPS value as below: taiji 9bdf5be dd59918(latest) with compositing 117 103 without compositing 170 165 xinit 161 160 EGL is choosing X's ARGB visual to match the GL ARGB visual, when it is supposed to be choosing the XRGB X visual, so the compositor is doing a bunch of extra work to blend the result. oh, this bug need to keep opening?
