--- Comment #2 from Sylvain BERTRAND sylvain.bertrand@gmail.com --- I went back to fedora 20.
The rendering is mostly ok. The "bloom" visual effects is adding a blue veil on the screen (see screenshot).
The character name display while selection is not rendered properly.
The anti-aliasing visual effect is killing performance.
