I've found a bug, the steps to replicate are:
1. Make many edits, in my case my first one was 'Develop'
2. Zoom into image
3. Change to Edits tab
4. Open the bottom/first Develop edit and change Exposure, zoomed image correctly updates
5. Now double click white dot to return Exposure to default, zoomed image goes pixelated and remains pixelated
