Version: 4.0 (using KDE 4.0.0) Installed from: Ubuntu Packages OS: Linux I disabled the panel buy editing ~/.kde4/share/config/plasma-appletsrc and commenting out the [Containments][2] section. Now there is a 1 pixel border at the bottom of the screen, and windows or widgets dragged down end up with a line of the wallpaper drawn over them at the very bottom. It seems to disappear when the desktop effects are disabled, the color of the line matches the wallpaper although it seems to pickup any applications/widgets that where there when desktop effects gets enabled.
There is no kicker and kdesktop in KDE 4, but plasma.
Created attachment 23146 [details] Screenshot. I've attached a screenshot of the issue. The line is between the two green dots. You can see the wallpaper is shown fully transparent here. I brought it up with Aaron a while back (when the svg changed) and he said it was a due to QT rendering issue. It's got something to do with an even number of pixels being stretched into an odd number of pixels area. Ex. a 48px svg image being stretched for 49px. I believe that was his explanation to this bug, and if that's the case I'm assuming we could fix the issue by expanding the panel 1 px so it becomes an even number again.
oh, yeah, this seems to be a bug in QSvg, that occurs when you extract an element id from the svg, once aaron said this should be fixed in qt 4.4, still not tried but i have hope :D as a side note: the problem is here also when compositing is off, but the black opaque background is hiding it
fixed with qt 4.4, snapshot of 12 Feb 2008
