1 Open inkscape
2 change tool to circle/ellipse and draw a circle
3 change tool back to selector/arrow
4 nothing happens for a long time, sometimes the tool preferences dialog appears but doesn't always finish drawing on-screen (it is semi-transparent)
I have tried hiding the rulers but the problem persists.
I can get the arrow/selector with F1 but then I can't select other tools
Inkscape 0.91 r13725 (although I have experienced similar on previous versions)
Win 10 Pro
Lenovo X1 Carbon Yoga
Intel i7-6500 2.5GHz 8GB 64bit Intel HD Graphics 250
how do I fix this
