When scrolling in Firefox (v.3.0.5) using xf86-video-intel-2.5.99.1 horizontal stripes appear in the text. This doesn't happen with version 2.5.96. My system: Debian/Sid kernel 2.6.26-1 Chipset: "852GM/855GM" Driver: module version = 2.5.99, compiled for 1.5.3
what's 2.5.96? Could you try git bisect?
(In reply to comment #1) > what's 2.5.96? Could you try git bisect? > I mean 'xf86-video-intel 2.5.96.0', a previous version from git://anongit.freedesktop.org/xorg/driver/xf86-video-intel. As it is only quite a minor bug, I am not going to try bisect, I am not used doing this. Sorry. These stripes appear only occasionly, they are not really disturbing!
The gray stripes occurring when scrolling Firefox still appear with version xf86-video-intel-2.6.0 In some apps characters are sometimes being rendered twice. These features are also mentioned in bug #18138. Driver : - xf86-video-intel-2.6.0 (compiled for 1.5.3) - libdrm2 v.2.4.3+git+20090105+a8c5480-1 (Debian/experimental) Kernel 2.6.26-1-686 (Debian/Sid v.2.6.26-13)
(In reply to comment #3) Both issues (gray stripes appearing when scrolling and characters sometimes being rendered twice) are fixed when using Option "MigrationHeuristic" "greedy" in Section "Device" of xorg.conf System: Debian/Sid kernel 2.6.26-1 (Debian/Sid v.2.6.26-13) Chipset: "852GM/855GM" Driver:version = 2.6.1,compiled for 1.5.99.901 Libdrm2 v.2.4.3+git+20090105+a8c5480-1(Debian/experimental)
Does xserver master have this issue?

(In reply to comment #7) > current master require drm git master. > OK, I compiled drm-master.tar.bz2 from http://cgit.freedesktop.org/mesa/drm/commit/ and copied the *.ko files to /lib/modules/2.6.26-1-686/kernel/drivers/char/drm Now xf86-video-intel-master compiles without errors but it still doesn't work. Xorg.0.log shows the following error: (EE) Screen(s) found, but none have a usable configuration. Fatal server error: no screens found
Both issues (gray stripes appearing when scrolling and characters sometimes being rendered twice) are fixed in xf86-video-intel-2.6.2 Option "MigrationHeuristic" "greedy" in Section "Device" of xorg.conf is no longer necessary. System: Debian/Sid kernel 2.6.26-1 (Debian/Sid v.2.6.26-13) Chipset: "852GM/855GM" Driver: version 2.6.2 compiled for 1.5.99.902 (xserver from Debian/experimental) libdrm: v. 2.4.5 Using kernel 2.6.28 also no more screen corruptions!
Thanks for testing! Close this now.
