I am running Synfig on Ubuntu 14.04 LTS and using a drawing tablet. I have tested the tablet and it works fine on Gimp. When I draw, I get this weird line glitch where the lines draw all over the screen, similar to how when you put your whole hand on an iPad while using a drawing app. How do I fix this?
Hello gamable and welcome here …
look like a bug … can you post your tablet hardware specification plus a screenshot of whats happen …
