I seem to have the same problem and it seemed to start right after the upgrade.
Every minute or so, sporadically I'll get line artifacts over a portion of the screen, generally every other line or so. It will clear up after a few seconds, but at times it will stay for awhile. Here's the important bits from glxinfo display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.2 client glx vendor string: Mesa Project and SGI client glx version string: 1.4 OpenGL vendor string: Tungsten Graphics, Inc OpenGL renderer string: Mesa DRI Mobile Intel® GM45 Express Chipset GEM 20091221 2009Q4 x86/MMX/SSE2 OpenGL version string: 2.1 Mesa 7.7.1 OpenGL shading language version string: 1.20 And the lsmod info without printing and sound modules Module Size Used by binfmt_misc 6587 1 ppdev 5259 0 dm_crypt 11331 0 joydev 8708 0 lib80211_crypt_tkip 7596 0 dell_wmi 1793 0 dell_laptop 6856 0 dcdbas 5422 1 dell_laptop wl 1959598 0 lib80211 5046 2 lib80211_crypt_tkip,wl dm_raid45 81647 0 xor 15028 1 dm_raid45 fbcon 35102 71 tileblit 2031 1 fbcon font 7557 1 fbcon bitblit 4707 1 fbcon softcursor 1189 1 bitblit vga16fb 11385 0 vgastate 8961 1 vga16fb i915 282354 3 drm_kms_helper 29297 1 i915 drm 162471 4 i915,drm_kms_helper i2c_algo_bit 5028 1 i915 usb_storage 39425 0 sky2 40775 0 video 17375 1 i915 ahci 32008 1 intel_agp 24177 2 i915 agpgart 31724 2 drm,intel_agp output 1871 1 video Let me know if you want any more info to help diagnose.
