Description Martin Flöser 2008-06-21 11:32:48 UTC
Version:            (using Devel)
Installed from:    Compiled sources

I have two activities defined. When I enter dashboard mode in first activity the result is as expected. The background is shown and the plasmoids are "floating" on top of everything else.

When I change the activity via ctrl+shift+n and enter dashboard mode only the widgets are shown and there is a white background. No more windows, no more floating.

This also happens when I change the activity via the zoom interface.

I will attach two screenshots to illustrate this issue.

i think this is a composite problem. i've seen this issue occassionally with even just one activity. can you turn desktop effects off and see if it persists? thanks =)
Comment 4 Martin Flöser 2008-06-23 10:06:32 UTC
With desktop effects disabled the background is shown on both activities.

Would it help to post the plasma-appletsrc?
Comment 5 Aaron J. Seigo 2008-06-23 22:32:47 UTC
thanks, but no, that's not necessary.

i used to see this issue as well, but it's gone away for me. it's related to kwin compositing, however. it needs to be investigated a bit more before i'd feel ok with moving it over to the kwin component, which is where it actually belongs.

partly white dashboard on single-screen mode

I do only have a simple activity. For me, a big part of the dashboard is white,
but not everything. The not-white part is actually translucent like it's
supposed to be.

This effect does not seem to depend on a particular KWin plugin: I deactivated
all of them and the white background was still there. Only disabling
compositing completely helped to remove the white background.

> Only disabling compositing completely helped to remove the white background

so it's an argb visuals bug in the video driver. as such it's an upstream bug which i can do nothing about.

as plasma is the first production app outside of WMs to really use argb visuals much, we're uncovering a lot of brokenness in video drivers =(
