Tried also disabling drm, doesn't change. Tried also using latest intel (2.9.1) driver, doesn't change. Tried with custom xorg.conf and default built-in configuration, doesn't change. here's an extract from Xorg log that shows the chipset: (--) PCI:*(0@0:2:0) Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller rev 3, Mem @ 0xb0080000/524288, 0xc0000000/268435456, 0xb0000000/262144, I/O @ 0x00001800/8, BIOS @ 0x????????/65536 (--) PCI: (0@0:2:1) Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller rev 3 Would be nice to offer a separate Xorg r7.5 port (without substitution of r7.4 wich is stable), to see if with the new server works, or investigate in freebsd/drm to see why there's that strange problem. I'm actually working with a kernel i configured/compiled, but problem is reproducible also with GENERIC. thanks >How-To-Repeat: always reproducible. start xorg and pay attention to the colors (using gnome with a blue background shows the difference really good. >Fix: >Release-Note: >Audit-Trail: >Unformatted:
