Hello!
I just updated to Cubism 5 recently from 4.2, and I'm facing huge amounts of lag in the editor when sliding parameters while an Artmesh or deformer is selected as well as additional screen tearing when "Randomize parameters" is activated.
While lag is also present on the previous version, it is not as heavy as in 5.0. I have also tried the workaround for High DPI displays, and even unplugged the second monitor, but it did not improve the performance. I have attached a screen capture of the comparison between 5.0 and 4.2 with the Hiyori sample model.
