White block phenomenon when using jetson nano+qt4 + opencv4.5 +UVC camera

Hello everyone, is there any white block phenomenon when using jetson nano+qt4 + opencv4.5 +UVC camera? Whenever the picture fluctuates greatly, the image will appear chopped and white. But when I switch the terminal interface to the topmost this problem is gone.

Seems like there’s a performance issue. Please executesudo nvpmodel -m 0 and sudo jetson_clocks to enable Jetson Nano in maximum performance mode. See if this helps.

thinks for your help,I power it with 5v4a. And has chosen to work at max performance. I used the method you gave and it didn’t improve.

Please try OpenCV + UVC camera and see if you can observe the issue:
