Review request for Plasma.


Repository: plasma-framework


Description
-------

Clearing the pixmap is actually wrong, because in some cases the IconItem::updatePolish() is not called when changing visibility.


Diffs
-----

  src/declarativeimports/core/iconitem.h e73829b 
  src/declarativeimports/core/iconitem.cpp 4f41b3b 

Diff: https://git.reviewboard.kde.org/r/128409/diff/


Testing
-------

Tests still pass.

The bug (no icon rendered) can be sometimes experienced in task manager volume controls and systray popup pin button. This patch fixes it.


Thanks,

David Rosca
