Hey!

I have a problem on my desktop, a strange square appeared, and i can not delete it.
I have tried to change my wallpaper, but it did not work.
I'm going to post a image here, of that strange square:

How can i fix this bug?

Thanks!

Have you tried deleting your cache? Try deleting the contents of the .kde/cache- (or .kde4/cache) and the .kde/tmp- (or .kde4/tmp-) directories.

Thank you for your answer.

It desapeared!

Hi, i have exactly same problem here, but deleting tmp and cache directories in ~/.kde4/ didn't helped.
And yes, i deleted directories it was pointing to, not only symlinks

Did you quit plasma-desktop first? If not, you can try that with the command

Code: Select all

kquitapp plasma-desktop

(Run plasma-desktop to start Plasma Desktop again.)

I've quit whole KDE first and did it at tty.
Then i was solving activities bug discutted here : http://forum.kde.org/viewtopic.php?f=67&t=90229, and when i made new plasma config, it was fine, but after some relogs(not first!) it appeared again

But when I've tried it now again, whit command suggested by you, it did the trick, so thanks for help

I've add some plasmoids to desktop, relogged and square is back! Here is my screenshot : http://shots.arteal.name/uglykdesquare.png

I have this "ghost window" too. For me it appears in the top left, I thought it was some resizing artefact, or some such. It comes and goes with no apparent reason behind it.

Notice that the border at either side has a discontinuity - I get the same sort of discontinuity in the shutdown dialog.

If you turn off Desktop Effects does it disappear?

Which version of KDE are you using?
I had this same issue some time ago, but after upgrade to KDE 4.5.3 problem has gone.

I have this problem on KDE 4.5.3 and yes, it disappears when I turn off desktop effects

Can you try turning off all the Effects then enabling Desktop Effects itself? Then try incrementally enabling Effects until it re-appears and post back here.

When I turn off desktop effects the square disappear. When I then again turn on desktop effects and leave other settings as they are, the square doesn't reappear. In addition when I move the taskbar to the left the square also disappear.

Is a common graphics card/driver in use here?
