As you can see, it has some errors. User-Agent: Mutt/1.5.6+20040523i Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 1478 Lines: 37 The radeonfb driver in 2.6.7 produces some interesting artifacts on scrolling, both scrolling horizontally and vertically. When scrolling vertically (in mutt, in slrn, in less) some lines move horizontally, and corruption occurs. Not all scrolling produces artifacts, but fairly often. When scrolling horizontally (most obvious in angband -mcu with the option 'keep the screen centered' on) corruption appears at once. Booting with 'noaccel' fixes the problems, but is slow, of course. 0000:01:00.0 VGA compatible controller: ATI Technologies Inc RV350 AQ [Radeon 9600] Kernel command line: root=/dev/md3 video=radeonfb:1600x1200-16@85 radeonfb: Found Intel x86 BIOS ROM Image radeonfb: Retreived PLL infos from BIOS radeonfb: Reference=27.00 MHz (RefDiv=12) Memory=324.00 Mhz, System=182.00 MHz radeonfb: Monitor 1 type CRT found radeonfb: EDID probed radeonfb: Monitor 2 type no found radeonfb: ATI Radeon AQ SDR SGRAM 128 MB Console: switching to colour frame buffer device 133x54 Any hints would be appreciated.
