Bug 271964

Summary: Kwin crashes and the computer slows down while using desktop effects
Product: [Plasma] kwin Reporter: Dmytro <dmytro.av>
Component: generalAssignee: KWin default assignee <kwin-bugs-null>
Status: RESOLVED DUPLICATE    
Severity: crash    
Priority: NOR    
Version: unspecified   
Target Milestone: ---   
Platform: Ubuntu   
OS: Linux   
Latest Commit: Version Fixed In:

Description Dmytro 2011-04-29 11:53:54 UTC
Application: kwin (4.6.2 (4.6.2))
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
trying to launch the applet (e.g. klickoff but it can be any other one) the computer slows down (this version of kde used to work normally with maverik). if i open a browser and try to open flash video in fullscreen, kwin crashes
- Unusual behavior I noticed:
transparency slows down my computer (on intel) very much. the systems disables all effects. after manual renewing the effects, the panels remains opaque and animations work seamlessly

-- Backtrace:
Application: KWin (kwin), signal: Segmentation fault
