By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Alexis PM 2012-09-19 12:11:46 CDT
KDM don't draw well the background, artifacts can be seen. I think I solved it with KControl > System admin > Login manager > Apparance > Compositor: Trinity compositor. If choosing Trinity Compositor solve the problem, the package should be reconfigured to do it by default.

I watched the garbage when I turned off the SAK, turned off Compositor and set themed kdm.

At start kdm was not displayed background image - only black. After logout instead of a background image or black screen I see garbage. After further research, I found that it only happens with SVG background image or if the image could not be loaded (for example, does not exist).

I found three problems:
1) SVG images are expected to be only 'svg', not 'svgz'.
2) When the image is 'svgz' is passed to loadPixmap that necessarily fails.
3) When renderSvg or loadPixmap fails, the image remains indeterminate => displays artifacts.

I'm just finishing up and test the patch...
