Sometimes, while I am using Krita with a tablet (Wacom Intuos PTK-640), and I use the scroll tool (the big button on my stylus), the canvas becomes unresponsive, and I am able to draw on or otherwise alter the painting unless I exit out of Krita completely and restart it. It seems to happen when I use that button on my stylus but it's possible it happens without me doing so (can't quite remember). Reproducible: Didn't try Steps to Reproduce: 1. Start Drawing 2. Use the big button on the stylus to drag the canvas if zoomed in. 3. Sometimes the canvas will become unresponsive. Actual Results: It seems to only happen randomly.
Could it actually be the same thing as https://bugs.kde.org/show_bug.cgi?id=358130 ?
Please try 3.0 as well.
