Bug ID: 388929
Summary: Weird crash while drawing. [GDB backtrace]
Product: krita
Version: git master
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: Brush engines
Assignee: krita-bugs-n...@kde.org
Reporter: griffinval...@gmail.com
Target Milestone: ---
I was drawing with the "Basic_Chisel_Smooth", which is a pixel brush. Even
weirder, it is a pixel brush that does NOT have any of the airbrush features
turned on.
I had GDB turned on.
I have no idea what happened. I am therefore afraid it might be a race
condition with multi-threaded brushes.
KDE Neon based on Ubuntu 16.04, with Intuos 3, build from master.
