Driver bug, it's induced (at least) by the blur effect - you can disable that in "kcmshell5 kwineffects"

Comment 2 ben 2015-09-04 23:23:54 UTC 
Please  what steps  do I need  to disable this as you commented   before  " in kcmshell5 kwineffects"  ?  How  can I access to kcmshell5, and using Konsole or GUI ?  Thanks.

kcmshell5--list_output

I accessed kcmshell5 using Konsole  and  asked  for  : ben@ben-Satellite-C645D:~$ kcmshell5 --list

and  I could not  see and  find  Kwineffects  in there, maybe it is not installed. Please  help me. Thanks
Comment 4 ben 2015-09-04 23:53:39 UTC 
Thannks anyway . I could do it using konsole  as : ben@ben-Satellite-C645D:~$ kcmshell5 kcmkwineffects 


I  saw  Desktop effects windows and  went  below till I found  Blur effects  as activated. So I deactivated  it and then clicked  apply  and  finally ok to close that Desktop windows ..  Now  I will try again and open  my Firestorm viewer 4.7.3 for second life game..  then use  volume buttons or  open a new application and  will let you know how I did later ..

Thanks  a lot Thomas  you were  right..I could access to kwineffects, disabled  Blurr and apply  my changes  ..I have not had   that crash  again .
