Some preparation for GFX's entry into low power

[Jack li1]

I want to get the MCU into low power mode,but I found that entering low power and exiting GFX would not work.So what should I do before going into low power?I used a DSI screen and DMA2D mode

Can you elaborate on "would not work" ? Thanks

​modle::Tick () in GFX is not executing.
