Xephyr performance work
-
Excess sync in put_image path (xorg/xserver!868 (merged)) -
xcb_image_sub_image is a trap -
xcb_put_image is a terrible API, so is xcb_image_put -
shadowfb for async upload -
bgpixmap/expose trick -
dirty tile detection in shadow -
solid fill " " " -
framerate throttling
And eventually:
-
Render with glamor with surfaceless EGL, glReadPixels, put_image to display server
