Bug ID: 402535
Summary: Krita memory leaks or endless loop when using freehand
brush with perspective assistant
Product: krita
Version: 4.1.7
Platform: MS Windows
OS: MS Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: Tool/Assistants
Assignee: krita-bugs-n...@kde.org
Reporter: genosim...@gmail.com
Target Milestone: ---
This bug leads to UI unresponsiveness after short time under certain
conditions. Task manager indicates huge memory usage(>4GiB)
STEPS TO REPRODUCE
1. create a new image(i used 64x64 pixel with other settings at default values)
2. Add a couple of connected perspective assistants to canvas
3. Choose freehand draw tool, turn "use assistant" tool option on.
4. I used simple pixel art brushes to trigger the bug, might work with others
as well
5. Draw several lines using assistant with the freehand brush.
OBSERVED RESULT
The bug is not triggered immediately, but after some short time(a couple
seconds in my case) you will notice UI becoming sluggish or unresponsive, and
the memory usage stat in the Task Manager will shoot through the roof.
EXPECTED RESULT
is obvious
SOFTWARE/OS VERSIONS
Windows: 7 x64
