This is true whether the brush is grabbed from the canvas or is from a single pixel.
Reproduce:
- Choose a brush. You can modify it, resize, etc.
- Change tool to Filled Polygon while on the canvas
- Move the cursors’ position on the canvas, away from when you enabled the tool; Try to draw with the tool. Try to pan as well.
- If you change the tool, the painted pixels will go away.
