Description Tanja Schulte 2009-11-08 19:52:48 UTC

Version:            (using KDE 4.3.2)
OS:                Linux
Installed from:    Debian testing/unstable Packages

Everytime I log into KDE (from KDM) the first I see is a white square in the upper left corner of the screen which seems to have the same aspect ratio as my display resolution and takes up about roughly 60% of the screen. It vanishes after one to three seconds after the desktop and wallpaper have appeared. It happens independently from the used graphics driver/card (nvidia, ati, intel, sis) and the display resolution and ratio. It looks like something is trying to open a window and can't or if the display size is calculated wrong and then expanding - at least it is nasty, ugly and doesn't look very trustworthy.

When I close windows maximized and demaximize them after reopening the application all application windows apparently revert to the size the white square had (Bug 214325). Maybe it isn't of any meaning but in case it might I just wanted to add it.

Confirmed.
It seems this bug is issue since KDE 4.3.0.
Debian Lenny/Sid

Hmm... All comments are of Debian. Maybe this isn't just a coincidence.

Same thing with OpenSUSE... KDE 4.2 worked ok, but after updating to 4.3.3 there is a white square in upper left corner for a while when logging in. 

May be the splash screen is just disappearing too soon? When I'm logging in I see that white square first, then desktop without background image. Background image is loaded 1-2 seconds later...

> May be the splash screen is just disappearing too soon?

Yes, i think so. Ksplash is waiting for "WAIT_STATE desktop", wich means that plasma-desktop is ready, as i read in documentations. But when ksplash dissapeares, plasma still isn't fully loaded. Just after second first plasma visual elements appearing.
Something wrong with WAIT_STATE checking?...
Where does Ksplash look to determine if WAIT_STATE is ok...

Comment 7 Matti Kettunen 2009-12-07 19:35:26 UTC

Just updated to 4.3.4... No more white square when logging in :)

Comment 8 Ilya Potapov 2009-12-11 08:47:02 UTC

I've partly updated to 4.3.4 and no more of this bug!)

Comment 9 Jonathan Thomas 2009-12-13 06:04:11 UTC

I'm marking this one as fixed since there have been several reports stating so. :)

Comment 10 Ilya Potapov 2010-01-28 09:17:17 UTC

It's very funny that mysterious white square nevertheless exists... It shows itself very rarely, but shows.

Comment 11 Christoph Feck 2010-02-24 03:14:29 UTC

Users that disable splash screen still see this annoying "first-open-with-default-size-then-maximize-to-full-screen-three-seconds-later" desktop on latest trunk.

Why doesn't plasma-desktop call showFullScreen() or use setWindowState(Qt::WindowFullScreen) before showing it?
