Bug ID: 386498
Summary: Crash with multithreaded brushes.(segfault with gdb
backtrace)
Product: krita
Version: git master
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Brush engines
Assignee: krita-bugs-n...@kde.org
Reporter: griffinval...@gmail.com
Target Milestone: ---
Might be related to 386497.
This one happens with predefined brushes while I was testing rad's sharpness
patch. As I cannot see sharpness mentioned in the backtrace, I suspect it is a
general bug:
