Description Michael 2013-10-11 00:14:06 UTC
Sometimes certain effects of menus leave shadows behind. A way to reproduce this issue is by using the 'Hilight Mouseclicks' effect. Clicking repeated times causes black fragments and shadow leftovers.

OpenGL renderer,
 KDE 4.10 and 4.11, kernel 3.11, same with nvidia-blob driver and 2.21 intel video driver.

Reproducible: Always

Screenshot showing the issue of leftover shadows.
Comment 2 Thomas Lübking 2013-10-11 09:46:10 UTC
screenshot looks like tooltip shadows, bug #324560 ?
Comment 3 Michael 2013-10-11 12:03:08 UTC
I accidentally set the KDE version to 4.11.1 while I do use x.2

Alos, I verified that the code from the other bugreport is applied:
draget-lap kwin # cat /var/tmp/portage/kde-base/kwin-4.11.2/work/kwin-4.11.2/kwin/events.cpp  | sed '1524!d'
        emit geometryChanged(); // update shadow region

Yet the rendering-issues are still present and reproducible by clicking around with the 'Animate Mouseclicks' effect turned on. qtgraphicsystem raster/native and OpenGL Version do not affect it, tested on an nvidia and intel machine.
Comment 4 Thomas Lübking 2013-10-11 19:42:55 UTC
Please attach the output of "qdbus org.kde.kwin /KWin supportInformation" then.
Do the artifacts stem from popups or tooltips or either (or nothing?)?
Comment 5 Michael 2013-10-11 20:59:07 UTC
It is the text-tooltip of the mouse-click effect. That overlays saying 'left' or 'right'.

It happens when I click repeatedly - when the tooltip does not disappear on its own but is interrupted by my clicks.

The output of my laptop with intel GPU:
draget@draget-lap ~ $ qdbus org.kde.kwin /KWin supportInformation

Comment 6 Thomas Lübking 2013-10-11 22:33:10 UTC
The information were obtained when the effect was disabled ... ;-)

Anyway, on top of the additional information, i could reproduce it.
Just to be sure: what settings do you use for the rings?
(Width, duration, radius and count)
Comment 7 Michael 2013-10-13 17:40:39 UTC
Default values:
width: 1px
duration: 300me
radius: 20px
count: 2
font: Sans Serif 9

It is really a minor thing. Just thought I help polishing the last pre-5 release =D

After the 4.10 -> 4.11 update my plasma config was messed up somehow (controlbar turned invisible?). But since I had changed so many settings and plasmoids, thought I try a clean config.
Comment 8 Thomas Lübking 2013-10-13 18:50:08 UTC
I couldn't reproduce it with similar settings, but given the code was pretty much nonsense, i don't wonder too much.

Since you're on gentoo, feel free to try the patch in the linked review request.

And "only a dead bug is a good bug", so it's appreciated to report them - no matter how small they are (I sense that I'll soon regret this statement ;-)
Comment 9 Michael 2013-10-13 23:01:57 UTC
Reading your last post I thought you *were* able to reproduce it. :-P
Anyhow. Patched, tested and it works rock solid!

If I knew it was only that silly effect and no deeper issue I would have left it alone. Thanks a lot, not only for polishing, but for all of KDE. =D
