It might be related to how the Drawing Board editing tool handles its canvas boundaries on the U11+, especially if certain areas become locked or non-interactive due to aspect ratio or resolution settings. I've noticed something similar when working on aesthetic drawings in certain apps, if the canvas doesn't scale properly or has built-in margins, the brush or pen tools can't reach those edges. Sometimes switching to a different resolution, cropping slightly before editing, or exporting and re-importing the image can help bypass that invisible boundary.
