Product: kwin
Version: 5.6.5
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: xpr1...@mail.ru
I have found a way to crash kwin/plasma in Kubuntu 16.04.1 on my system
(pentium g860, 8Gb, integrated video) and in Virtual Box. The method works in
freshly installed VM, live CD VM, live USB my system, and in my installed
system (which is based on ppa:kubuntu-ppa/backports).
In a fteshly installed VM system the result is a report about plasma crash that
instantly closes.
In live CD vm system and live USB VM systems kwin obviously crashes but there
is no report appear.
In my real system a report about a kwin crash appears.
Reproducible: Always
Steps to Reproduce:
1. boot the system (live usb/cd Kubuntu 16.04.1, freshly insalled Kubuntu
16.04.1, VM or may be your real system)
2. Press: Application Launcher - Applications - Settings -System Settings -
Applications Style - Window Decorations - Select Plastic - Apply
3. Press: All Settings (the back button) - Input Devices - Touchpad - Joystic
(or other tab, or back) - Discard
4. Close the System Settings window by clicking on the "X" close button
5. Do again: Application Launcher - Applications - Settings -System Settings -
Input Devices - Touchpad - Joystic (or other tab, or back) => KWin crash
If you open any other windows before or inbetween, the method may not work.
Actual Results:
In my real system (kubuntu backport) a report about kwin crash appears
In a freshly installed VM system after right clicking on the task button and
trying to close the System Settings window for a couple of times a plasma crash
report appears and instantly closes. The System Settings window doesn't close.
In live cd/usb systems nothing appears but I couldn't close the System Settings
window in a usual way because it had no caption and nothing happend when I
tried to close it by the method above..
Expected Results:
the window about applying changes appears as usual and the System Settings
window can be closed in a usual way
