Running win10 1903 on a ryzen 5 2600x, 32gb RAM w/ radeon rx580 8gb and 2 monitors and a Wacom Intuos CTL-6100x . Purchased 1.7.1.404, and was playing with the paint tools in photo. It's crazy. As soon as the cursor leaves the image window the pointer jumps - if I'm trying to access the toolbar on LHS it jumps to the adjoining monitor far left, if RHS, jumps to image left. Does not do this with mouse. If I try and use paint brush, it will only draw a straight line between where I touch pen down and where I lift it off. Sometimes the mouse behaves in this way, sometimes the pen works - cannot see any logic. Many other issues - eg neither pen not mouse will drag zoomed image even though it says "Drag to pan" at bottom LHS. Drag left in zoom does not zoom out. Drag + alt does not zoom into marquee but zooms out. And so on. Is it me or is this really buggy software?
