This just means your PC is not fast enough to sample at that speed and update the window. Try keeping the sample rate low.

hello all
when I run uhd_fft.py and change sample rate from 1 to 2 the graph is being locked and i couldnot change anythig,
what is my fault?
Thank you.
Also try using:

fft-rate 5 --averaging

to reduce the number of updates, which also helps.
