Description iryna3074 2011-08-17 20:03:34 UTC 
Application: kwin (4.7.00 (4.7.0))
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
Al passaggio video a schermo intero  va a scatti per un pò,  si pianta e non va più nessun comando tranne ctrl f10 che lo fa tornare a dimensioni normali, ho provato a installare varie volte sia i driver scheda video che il flash player,  con nessun miglioramento anzi direi proprio quasi un peggiormaneto della situazione.
Un grazie

The crash can be reproduced every time.

I'm sorry, but I do not understand what you wrote. Could you please rephrase in English language.
Comment 2 Thomas Lübking 2011-08-17 21:59:22 UTC 
He mourns about (flash related, i think) jerkyness when starting, stopping or running (i don't know) the present windows effect ("out of cpu" issue, i'd say)
And that installing video drivers didn't help.

The crash is obviously unrelated (or my lousy italian _really_ sucks ;-)
Apparently a window got closed during the effect deactivation (at this point the view has been deleted and is Null, but the window list isn't empty)

@iryna3074:
Nevertheless please report future bugs in English _only_
It vastly raises chances that your problems will be solved.

Also post your HW specs (CPU/GPU, GPU driver & version) for performance related issues.

To lower the jerkyness while _running_ the present windows effect (NOT while it's starting or stopping) set the scale method to "smooth" in "kcmshell4 kwincompositing", 3rd tab
Comment 3 Martin Flöser 2012-03-09 07:22:59 UTC 
The crash report is unfortunately missing information about how to reproduce the crash. As well the crash has been reported against 4.7.0, so there is a chance that this crash has been fixed in the mean time.

In case that you are still able to reproduce the issue with a recent version (at the time of this writing 4.7.4 or 4.8.1) please provide a new backtrace and the steps to reproduce the crash. Thanks.
