Right now the auto-scroll sometimes gets stuck with tools that have it enabled. This makes Krita difficult to work with as trying to pan back to the canvas auto-scrolls it to outside the canvas again.
I cannot get it to reproduce 100%, but this is the closest I can get to steps to get it.
- Create a new canvas (1600 x 1200)
- Select Crop Tool and click on the canvas (selecting the bounds of the canvas)
- Hold down the space bar while in the active canvas area
- Repeatedly try to pan the canvas from in the canvas area to the lower right GUI area with the zoom slider.
I tested it on Ubuntu 17.10 VM. It seems to get stuck about 30% of the time.
