Description Dmitry Kazakov 2011-07-14 06:34:29 UTC
1) Turn on build-up mode in the brush
2) Start painting something
3) Press Ctrl+Z a couple of times during the stroke

The canvas will go into a weird state. Some parts of the canvas will be undone, some not. After that Krita may crash on exit.

I'm trying to solve this issue within the strokes framework right now.

Git commit 3a6d6d7b2c6c6de81b6a0a3b850dbe3e07e13f2b by Dmitry Kazakov.

Pushed by dkazakov into branch 'krita_strokes_framework_kazakov'.

Added our own undo stack

The new stack doesn't start undo/redo if there is any processing
in progress. We might add block/unblock() calls to the stack, but
this will be very inefficient, due to the huge synchronization
