Bug ID: 361836
Summary: High CPU usage when I open the applications launcher
Product: plasma4
Version: unspecified
Platform: Ubuntu Packages
URL: http://i.imgur.com/b8jTBGa.png
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: containment-desktop
Assignee: plasma-b...@kde.org
Reporter: scitech...@gmail.com
CPU usage increases a lot (from 0-2% to ~30%) and it keeps high all the time
when I open the applications launcher by clicking on the desktop with the
mouse.
This is the applications launcher I'm mentioning:

The problem is not happening using the other menus, like KDE menu in both
versions (Classical and default).
I changed the icons to the default, I disabled Kwin, I switched xrender, OpenGL
1.2, 2.0 & 3.0, disabled vsync, I changed the button of the mouse, and I even
renamed to ~/.kde folder in order to reset the KDE settings to find the
problem. But the bug persists in all this conditions.
The bug doesn't occur using clearlooks, CDE, Plastik or QtCurve. Only in
Oxygen.
Reproducible: Always
Steps to Reproduce:
1. Open the Desktop Settings, go to Mouse Actions
2. Select the Applications launcher in one mouse button
3. Now click the configured button in the desktop and check how the CPU usage
increases. Navigate through the menus, all the menus, and the CPU usage will
increase even more.
Actual Results:
CPU usage increased a lot and it stays high until I reset the computer. See the
screenshot attached: http://i.imgur.com/b8jTBGa.png
Expected Results:
CPU usage should decrease to normal values after opening the menu, or at least,
after closing it. CPU usage gets stuck in high values when it shouldn't.
I'm using KDE 4.13.3 (this version was not in the list).
For me, I can stop using that menu and it's not a big problem. I use Krunner
most of times and I like it. But knowing there's a bug I wanted to notify you.
I was not sure if to publish that bug in Oxygen section or plasma4. I decided
to publish it here because it's an option from the plasma settings. There's a
correlation between this bug and Oxygen, but that doesn't mean there's
causality.
