Hi, all,=C2=A0

Just upgraded= to KDE 5, Qt 5 (as full as possible) and now QtCreator frequently uses alm= ost full CPU, a quad-core i5-4430. Any change on the IDE, even just passing the mouse cursor ov= er elements of an opened source code file, makes the CPU consuption to the = high tops.

It also happened when I tried some widgets using plasmashell, lik= e the analog clock and the Desktop widget. The process "plasmashell&qu= ot; eat up all available CPU cicles.

Could it be something related to more d= eep details inside Qt basis?

Turns out to find funny QtCreato= r's description on KDE menu: "Lightweight IDE for C++ ...".
Any hints to find out what is happening will be highly ap= preciated.

Best regards,
Francisco
