I am experiencing very strange screen corruption with the new Catalyst 8.5 driver on Gentoo with my Radeon X1950. I am using Bigdesktop with two Screens of 1280x1024 each. Every application has weird looking fonts. The graphic parts of any window seem to be fine but all spots having labels etc seem to mirror the other screen's picture. You cannot read any written letter on the screen. This is most fatal on konsole - there is no real letters but a mirror image of my other screen. This has come with this driver release, never seen this before with any driver. It applies from kernel 2.6.23 to 2.6.25 I am using at the moment. As it seems this is not different with a single-screen setup. When rmmod'ing fglrx the screen is fine, but no hardware acceleration. If I set Option "NoDRI" "true" in xorg.conf, this applies, too. The screen is fine again. I tried a lot of combinations in xorg.conf: Option "UseInternalAGPGART" Option "VideoOverlay" Option "OpenGLOverlay" Option "mtrr" Option "PseudoColorVisuals" Option "Stereo" Option "XAANoOffscreenPixmaps" Option "Textured2D" Option "TexturedXrender" -> either of them on or off. Option "UseFastTLS" "1" 0, 1, 2 -> changes nothing This is specific to qt applications only. No corruption in Java/Swing/AWT appilcations,GTK is fine, too. This could be the qt font renderer. I will update my qt and its dependencies. But this looks a little bit like a buffer overflow or something in the font renderer or the new ati-driver as it copies information of other pixels into the background of fonts and only occurs with the new ati-driver in DRI-Mode.

This applies to Linux-2.6.23-r8, 2.6.24-r8 and 2.6.25-r4, too.
I get video corruption with 8.493 as well, but I don't even have qt installed. Window borders remain during window drags, various windows like firefox or xterm have their contents miniaturized and stuck in random places on the screen, or tiled across the bottom edge, etc. Downgrading to 8.476 (hacked to compile with 2.6.25, see bug 218992) fixed it. (obviously I didn't have these corruption problems with earlier versions of ati-drivers, either) currently running vanilla 2.6.25.1 with a radeon 2600xt. (rv630) This is ATI's problem, not gentoo's. I'm just posting here for informational purposes.
If you want to use the latest drivers without corruptions, you need to do the following: - remove /etc/ati/amdpcsdb - set a virtual resolution that is maximal, that means, which is never exeeded at runtime in /etc/X11/xorg.conf. Here an example for maximal resolution 1280x1024: Section "Screen" Identifier "Builtin Default ati Screen 0" Device "Builtin Default ati Device 0" Monitor "Builtin Default Monitor" DefaultDepth 24 SubSection "Display" Viewport 0 0 Virtual 1280 1024 Depth 24 Modes "1280x1024" "1024x768" "800x600" "640x480" EndSubSection EndSection That fixed the bug on my system.
------- Comment #11 From Lukasz Goralczyk 2008-06-19 03:41:12 [reply] ------- Looks like its fixed in 8.6 (8.501) version of the driver.
