Since xf86-video-ati-7.1.0, only the r600g driver work (radeon before). On my Lemote 8133 Laptop with Loongson3a and RadeonHD 3200, text color (and some other like scrollbar background) is corrupted. As you can see in the picture only when 2DAccel is activated. The wm (i3) and gtk apps appear with red/yellow text (which change sometime when scrolling). Text in urxvt and imagemagick "display" are ok.

> Option "MigrationHeuristic" "greedy" What if you drop that option? Which version of pixman are you using? Does it happen with both exa and glamor?
Pixman 0.30.0 Same problem witout MigrationHeuristic... But i can only try with EXA because glamor doesn't work. See my Xorg.0.log. There si an undefined symbol (fbCreatePixmap) in glamoregl.

Ah, I only now noticed that you use not xf86-video-ati but the r600g driver. That is the xorg state tracker from mesa, which is unsupported and known to cause rendering issues. Unfortunately neither Gentoo x11 team can nor upstream will help you with problems on r600g.
Since the 7.1.0 upgade ox xf86-video-ati, i can't use radeon driver. X can't find screen with radeon. X -configure give only r600g. I've not changed anything, just upgraded to 7.1.0. X can't start with radeon in xf86-video-ati-7.1.0 but can in xf86-video-ati-7.0.0. I'll try to remove mesa[video_cards_r600]...
Please open a separate bug for xf86-video-ati problems.
Some big endian fixes have gone into Mesa since this was filed. Try a newer version. If that doesn't work, file a bug upstream.
