Hi,
I installed Adobe Air on my 64bit Kubuntu 8.10 KDE 4.2.

Air applications run fine until I minimize them to tray (twhirl, tweetdeck). If I then try to restore it, my Desktop (Kwin) comes unreaktive (I see flashing window borders), can't even switch applications anymore (have then to kill the AIR process from another tty command session)

If I turn compositing off, everything works as it should.

Anyone has a similar behaviour with AIR?

Well, I don't use those specific air-apps but I do use some air-apps occassionally and I have so far not encountered that problem.

I'm using air 1.5.1, on OpenSUSE 64 bit, with compositing turned on. In my case, using a nvidia-card using driver 180.29.

I am using Kubuntu 9.04 beta, KDE 4.2.2, Adobe Air 1.5.1.8210, Twhirl 0.9.2, nVidia driver 180.44.

If I turn on desktop effects, I get the problem described. It seems that Twhirl is restoring from the "systray" then minimizing to it again in and endless, fast loop. Only way to stop it is to power down by pressing the button on the pc.

This could of course, be a problem with all of the above mentioned packages. But it needs fixing. I hope someone can look into it and do something about it.

as you got exactly the same problem as I we should file a bug for KDE.4.2 then.

I have the same problems with other Air Apps, however it does not always crash KDE, sometimes I just can't restore from tray and I turn off the desktop effects so that I am able to see it.

I'm on Kubuntu 8.10, latest AIR and Kde4.2.2

Or maybe against air, or the apps in question. Has any of you with this problem tried the same app in gnome to see if it behaves the same way? Or with a different window-manager like metacity or compiz? That sounds like a good place to start to see where the problem may be.

This is why I find this particular problem a bit difficult. It is running fine without desktop effects, and I wish someone with an ATI board using their drivers would check it.

I am not going to test it with Gnome as I am trying to keep the system as clean as possible. And I do not have any other PC with a similar setup...

I could try to post this is the general Ubuntu forum and ask if anyone has seen the same problem there.

Soo... What is the effect of turning this one off? I set it to Never, and things are working fine.

Setting it to the default of "only for shown windows" should be fine as well. It's only noticeable if you have a log or video or something playing on another desktop and want the window to show the new contents in thumbnails/desktop grid. We need to do a huge hack for minimized windows so that's why we recommend against using it.

I'm having the same problem. Unfortunately I've tried removing all desktop effects but it still crashed KDE completely and didn't recover.
