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. – Marcus L.

Yes, even after a fresh reboot there is still a delayed reaction while dragging about blocks in GRC. GNU Radio Companion 3.7.5git-194-g76a271ac Ubuntu 14.04 x64 LTS Quad Core i7 Mike – Mike J.
