It's wrongly detecting your mouse as a tablet. Go to the preferences, and set "Mode" to "Disabled". This will disable graphic tablets (pressure sensitivity) in general, and thus also prevent from accidentally putting your mouse into screen mode (which is what screws up GTK).
The problem should already be fixed in the latest MyPaint release (v1.1.0) I think. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1168965 Title: Can't Paint / Broken Package To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mypaint/+bug/1168965/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
