Short description of error
Displaying a large image in the Image Editor impacts performance, mostly in the editor's UI itself, but as well in viewports with certain modeling tools.
The behaviour is not consistent, but seems to occur in spikes. In my experience it's most noticeable with 4k+ images.
Exact steps for others to reproduce the error
- Load or create an image of several thousands of pixels (10K x 10K).
- Zoom out until you see whole image
- Play animation
The Image Editor's UI now exhibits a low frame rate and long response times.
