During work often the canvas "locks up" and doesnt show the correct layer if i go to another layer with isolate canvas active. I need to then go to the next frame or previous frame to "unlock/refresh" it. from then on it doesnt trigger,untill i start drawing again https://www.youtube.com/watch?v=vZPzMbEI1ZQ&feature=youtu.be You can see in this video. The ONLY shortcuts I use are "layer up/down" "Isolata layer toggle" "previous/next frame" i can trigger this bug without much issue.
