I recently started a new build since 3.8 came out, installed my initial stack including sk.
Something was wreaking havoc in the editor, delays / stutters when interacting with the ui.
I disabled all browser plugins, then went through wp plugins one by one. It turned out Swiss knife was the culprit.
I didn’t have time to go through each setting to narrow it down further, I still may.
I’m unsure if I missed a post or if there was any known issues?
