/var/log/Xorg.0.log
Screen shot from the gentoo bug: http://bugs.gentoo.org/attachment.cgi?id=156359&action=view And this is on r5g6b5: (II) RADEON(0): Pixel depth = 16 bits stored in 2 bytes (16 bpp pixmaps) (==) RADEON(0): RGB weight 565 So very likely this is a bug in the SSE2 code operating on r5g6b5. In pixman-0.11.6, the sse2 fast path code can be disabled at configure time: configure --disable-sse2 If someone could test and see if this makes the bug go away, that would be interesting. Also interesting would be to know whether the bug depends on font rendering configuration, in particular whether it happens when the font is set to something other than subpixel antialiasing. Fixed in master Would you please post the patch or a hint where to get it? And in what version (if already released or the next release number) is that fixed? Thanks.
