I interfaced Camera to the STM 32f746G . i used pixelData widget to show the camera feed and created GUI above it. the problem is that i have tearing when i am using GUI on top of the pixel widget. I think its synchronization problem

I made touchgfx update the 2 layers instead of 1.

i have another issue which is that i want to display the live video with alpha = 255 but for the widgets its not possible because it will override the live video. is there way to not blend the whole top layer, only the widgets
