I am trying to make a program to get data for intel realsense d415 rgb-depth camera using qt on up board.
I tried to get frames from the sensor and it works good and the speed is normal and I can reach 30 fps.
Bu as I start rendering the color image on the GUI the frame rate goes down to 4 fps!
I just display a simple 2d image in a label at the GUI.
I am using Ubuntu 16.
is there any problem with graphics on up board?
And is there any way to solve this problem and speed the program?

Are you using GPU hardware acceleration?

It depends on how is your program and the libraries you are using, it is not specific to the board.
