Bug ID: 365367
Summary: Kwin always crashes when I try adjust the scale of a
bitmap image in MTPaint
Product: kwin
Version: 5.6.4
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: rb03...@gmail.com
Application: kwin_x11 (5.6.4)
Qt Version: 5.6.1
Frameworks Version: 5.23.0
Operating System: Linux 4.6.3-1-default x86_64
Distribution: "openSUSE Tumbleweed (20160625) (x86_64)"
-- Information about the crash:
1. Opened MTPaint and opened a bitmap file originally scaled at 22 x 22 px
2. Navigated to Image -->Scale Canvas
3. Clicked on the resize up button to increase the size of the bitmap to 80 x
80 px
4. This always freezes up followed by kwin_x11 crashing
5. I can replicate this every time
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
