Editing medium-to-large flow-graphs in GRC now *agonizing* slow

GNU Radio

Has anyone else noticed that in recent GR, medium-to-large flow-graphs
are now agonizingly slow to edit, even on relatively-capable
machines?

Larger graphs were always a tad sluggish, but it has now gotten to the
point that larger ones are nearly uneditable, and medium ones are
agonizingly sluggish.

Yes, even after a fresh reboot there is still a delayed reaction while
dragging about blocks in GRC.

Thanks for pointing it out. I believe I found the problem. Here is a
fix:

What’s the best way to apply this to master/HEAD ?

Just applied this. No perceptible change in sluggishness.

Sylvain’s patch was more effective, but had side-effects when using
grcc.
