### Gnome has graphic glitches on Fedora 19 with a Radeon HD6870

I have just installed Fedora on my computer, and got some very big graphic glitches. Here is the thing :

1/ I installed Fedora and noticed there was no sound on HDMI, so I decided to install the amd proprietary drivers to see if it changed anything (back on windows the hdmi sound was linked to my graphic driver so...)

2/ Restarting my computer, I had a black screen instead of the login screen. Couldn't switch to console mode either.

3/ I used grub to boot in console mode, and uninstalled the catalyst driver I just installed

4/ Back to Fedora, working fine as before, but enormous graphic glitches : Every system icon/font is completely destroyed, with random white pixels everywhere. It happens on the top bar, and also on every image/text when I activate the menu (windows key. I don't know how it is called). I looks like that on the topbar (couldn't make a screenshot of the menu, but it's the same on all the screen)

5/ I learned that there was a default amd driver (the free drivers) I tried to uninstall them just to see. Fedora worked but with a gray screen, so I reinstalled these default drivers. At this point I am supposed to have the original drivers that were on my system after Fedora's installation, but the glitches are still there :(

6/ I checked /var/log/messages to see what's up. There is an enormous amount of GL errors like that :

Just to check, I tried to launch a movie on xbmc, it worked perfectly fine both on windowed and full screen mode, so I guess the graphic card works with Fedora, there is just something weird happening between it and gnome.

Sorry for the long post, I prefer to say any information I could find
