Attachments:	A still captured from the effect combination (zoom + track mouse) This is the correct way of seeing "track mouse" (without "Zoom" effect)

Description Rafael Linux User 2014-04-03 10:53:43 UTC

I detected a bug in KDE 4.11.5 (OpenSUSE 13.1 x64) desktop effects.
"Track mouse"  effect combined with "Zoom" effect, under certain escenario, do strange things.

Reproducible: Always

Steps to Reproduce:
1. Enable "Zoom" and "Track mouse" effects. 
2. Configure the "Zoom" effect and select "Disabled" in "Follow (or track) the mouse" combo box.
3. "Accept"
4. Apply a zoom to the screen (using shortcut to "zoom" the scrreen) and activate "Track mouse" effect shortcut.
5. Move mouse pointer while "Track mouse" effect is on. 
Actual Results:  
As you can Mouse pointer is located separated of the "arcs" and they are spinning around some other center.


Expected Results:  
"Arcs" of animated "Track mouse" following the mouse pointer and sharing the same center.

Mouse and "track mouse" animation are not sharing the same point center, and the "arcs" of the animation neither.

A still captured from the effect combination (zoom + track mouse)

The two arcs are moving respect different centers (we are in zoom mode, remember that)
