But with semi-overlapping planes you would accomplish the same, without alpha dependency. Something like this? [BG] [Sprite 1] [Cursor] [Primary] [Sprite 2] Perhaps primary fullscreen to prevent issues with hw that doesn't support partial planes? ~Maarten _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
