Capture of the tray icon generated by KStatusNotifierItem::setOverlayIconByName
looking good
DESCRIPTION
While trying to implement the tray icon on Linux for Thunderbird[1], I think I
discovered a bug in KStatusNotifierItem. Using
KStatusNotifierItem::setOverlayIconByPixmap to overlay a badge on top of the
tray icon makes this tray icon all blurry. Also the overlay icon seems
misplaced and slightly clips through the edges of the tray icon. I attached two
captures of a tray icon showing this problem to this issue and created a small
C++ project to demonstrate the issue.

STEPS TO REPRODUCE
1. Clone https://github.com/christophehenry/plasma_overlay_icon_pixmap_bug
2. Compile and run main.cpp
3. Click on the button that appeared to switch between
KStatusNotifierItem::setOverlayIconByPixmap and
KStatusNotifierItem::setOverlayIconByName implementation.
OBSERVED RESULT
There's a difference between KStatusNotifierItem::setOverlayIconByName and
KStatusNotifierItem::setOverlayIconByPixmap implementations. In particular,
when using KStatusNotifierItem::setOverlayIconByPixmap the tray icon appears
all blurry and the overlay icon clipped out
EXPECTED RESULT
Tray icon generated by KStatusNotifierItem::setOverlayIconByPixmap should look
exactly the same as tray icon generated by
KStatusNotifierItem::setOverlayIconByName.
