Description Adam C 2012-01-10 14:07:51 UTC
Version:           svn trunk (using KDE 4.7.4) 
OS:                Linux

if dy scale is negative in the particle brush and you start drawing something, then the particles escape into the opposite direction. if it escapes too far, it's not possible to draw anything any more or to clear the scratchpad.

the same happens with the drawing area.

moreover krita fills up the memory, eats cpu and doesn't want to quit.
Comment 2 LukasT 2012-01-11 09:30:07 UTC
Confirmed. I will take a look.
Comment 3 Dmitry Kazakov 2013-09-26 18:22:33 UTC
Can be reproducible with a touchpad. It might be probably related to the Indirect Painting, because the scratchpad can be *cleared* *partially* even when the scratchpad's scheduler has hung.
Comment 4 Dmitry Kazakov 2013-09-26 18:23:07 UTC
There is no dataloss, but Krita should be restarted to get rid of it.
Comment 5 Dmitry Kazakov 2014-01-09 10:44:34 UTC
The usual canvas can also be hanged-up :( So data-loss is present

Fix the hangup when the Particle Brush is used with negative scale

The negative scale makes the equation unstable, but it still might be
interesting for the painter.
