Binary package hint: xserver-xorg-video-intel
I just upgraded from Intrepid to Jaunty. One consequence of the upgrade was that I'm now seeing some sort of cross-application rendering bug -- horizontal black lines show up in various apps.
To reproduce:
1) Open firefox to a long-ish page.
2) Hold down the "down-arrow" key to scroll downwards.
3) Occasional scattered black lines will appear overlaying the page content.
The lines survive incremental scrolling, but any kind of forced redraw (another window moving in front of them, scrolling the location where they appear off-screen and then back again, etc.) gets rid of them.
Observed in firefox (as mentioned above), GNU emacs, and then they showed up in the Gnome screenshot dialog when I was taking a screenshot for this bug report too... screenshots attached.
This is on a Thinkpad X60 with Intel 945GM integrated graphics, using EXA for acceleration. I do not use desktop effects of any sort (plain ol' metacity). My font hinting is set to use sub-pixel smoothing, "RGB" order (not VRGB).
I don't know for sure that it's an X server bug, but assigning to xserver-xorg-video-intel because the corruption seems to occur during within-server scrolling blits, at least sometimes. |
