Fritzing lags a lot

I was trying to create a simple circuit on a protoboard and Fritzing keeps lagging.
Core i5 11th
16gb Ram.
I don’t think specs are the problem, right?
What may it be?

How large is the perf board? There are (or were they may have been fixed) performance problems with large perf boards. If you upload the sketch (the .fzz file, upload is 7th icon from the left in the reply menu) one of us can try it and see if we have the problem as well.
