Bug ID: 400534
Summary: Flash in Firefox in fullscreen mode breaks
plasmashell/KWin
Product: plasmashell
Version: 5.14.2
Platform: Neon Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: paulo76.alga...@hotmail.com
Target Milestone: 1.0
SUMMARY
Flash in Firefox in full screen breaks plasmashell/Kwin, every time I put a
flash video stream in full screen mode the plasmashell crashes (but no crash
report is generated by the system).
In order to get things working again I have to close the Firefox tab that has
the flash video and run the commands:
killall plasmashell && kwin && plasmashell &
STEPS TO REPRODUCE
1. In Firefox browser go to a website that has a flash video, in example:
https://student.testmasters.com/portal/online/Test.aspx
2. When the video starts, put it in fullscreen mode.
3. Plasmashell/KWin should crash right away
OBSERVED RESULT
plasmashell/Kwin crashing
EXPECTED RESULT
plasmashell/Kwin not to crash
