    Description

      Reading framebuffer memory is extremely slow and should be avoided. It significantly slows down responsiveness of user interface. Haiku use RAM screen backbuffer to avoid framebuffer reading.

      I looked in ReactOS video driver/GDI implementation code some time ago and found framebuffer reading on ScrollDC.
