Public bug reported:
Binary package hint: kwin-kde4
I am using kubuntu Hardy / KDE4.1 on a Lenovo X60 tablet. I have desktop
effects turned on, and everything looks great, very smooth animation,
except: the screen redraw does not synchronize with vblank. I have tried
clicking "Use VSync" in the Effects options, but no change.
The tearing I am seeing is usually pretty subtle. It is most noticeable
when vertical lines are moving horizontally across the screen (ie
dragging windows, panning large photos, etc.). When it is noticeable, it
makes a shimmering/ripply effect that really detracts from the overall
smooth feel of KDE4.
My graphics hardware:
Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated
Graphics Controller (rev 03)
My xorg.conf is attached, please let me know if you need any more information.
** Affects: kdebase-workspace (Ubuntu)
Importance: Undecided
