There is a strange bug in Xpresso Editor (including Redshift Editor). When you start panning the view it sometimes flies away by no reason. It doesnt matter whether you use a hotkey or drag using the pan controller. At the same time zoom works fine. In fact, the bug occurs in about 1 case of 5. But it's unpredictableness annoys very hard 🙂 I wonder if anyone else has stumbled onto that.
