1st some background. I bought the full version of this app years ago. I loved it and used it as my main art app. Sadly, over time the app became unusable. Constant crashes and glitches. Layers would go blank & shift around. Saving would reduce the image quality until pixelated. Eventually the app wouldn't even open. I was really excited for painter 7. I thought I'd have a working paint app again. but the glitches are back. Many layers of my project are blank and offset upon opening. Unusable.
