Description omega 2010-05-08 11:45:05 UTC
Version:           unknown (using 4.4.3 (KDE 4.4.3), Kubuntu packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.32-22-generic

Quite frequently, my display "semi-freezes". I can move the mouse cursor and audio keeps playing but everything else freezes (video, etc). For example, if I click on kickoff, i see menu but i can't click on any application; if i click on skype tray, it open kopete window, etc...

you mention two plasma cases (kickoff, systray). Does that also happen when using non-plasma applications?

it happens when i use plasma and not-plasma applications.
Comment 3 Thomas Lübking 2010-05-08 17:58:41 UTC
are you saying that
a) video playback freezes (like frozen frame, sound plays on), but
b) you can call kickoff, the menu appears (and the screen is updated), but
c) you cannot interact with kickoff, despite you could interact with the plasma panel / desktop?
d) if you click on any systray icon, the click is passed to the wrong item (skype -> kopete), yet the window opens (and this is still related to the frozen video??)

most of the bugreport sounds like a mousegrab, but the frozen video sounds like a bug in Xorg or the compositor.

- Are you using compositing btw? ("desktop effects")
   -> does it happen without compositing?
- What's your GPU / driver

according to me is a mousegrab, i'm using compositing and if i disable compositing, the problem doesn't go away. i have nvidia 9600 gt ddr3  with nvidia proprietary driver (195). 

EDIT: i don't have video problem

likely a grabbed pointer or frozen focus.

- does anything aside from plasma (desktop, panels, kickoff) receive clicks then?
- can you change the focus using alt+tab? (and then eg. type into an open kwrite)
- does changing the decoration (eg. oxygen to kde2) help?
- can you "altf2" (open krunner) and fire "kwin --replace", does that clear the stage?

(maybe related to #226052)

i can change the focus using alt+tab but i can't write into an file o into a chat windows..i can write into konsole only if i launch konsole with krunner. next time, i'll test if kwin --replace clear the stage

seems that removing .dbus folder, the problem is solved...maybe, this depends on feature that allow to restore applications remained open in the previous session...but i'm not sure
Comment 9 omega 2010-05-26 21:22:03 UTC
I was wrong ... I am noticing that this error always happens while using chromium browser
Comment 10 Thomas Lübking 2010-05-26 22:51:12 UTC
a) please specify "using" (just starting, browsing, entering a flash powered page, typing sth. into the url bar...)
b) do you use chromes internal titlebar and iff, does the problem remain if not?
c) what's your focus policy?
