Package: xserver-xorg Version: 7.1.0-10 When I drag a window or resize it, I get artifacts left over from that operation. Also, some 'normal' rendering operations are affected, I even see some weird light-effects in Quake 2.
Now, those artifacts are not completely random. I used an Eterm in Enlightenment (I normally use fluxbox, I only used E because it displays position and size while moving/resizing) and positioned it at different positions and then used the resize-handle to create the rubber-band rect that shows the target-size. The results are X Y artifacts from 330 116 left side of rubberband 330 117 - 331 116 right side of rubberband 331 117 right side of rubberband 332 116 left side of rubberband ... I tried some more positions, the common factor seems to be that the X position is odd. Another similar effect occurs when moving a window. Just grab the window and wiggle it around a bit and you have the pixels all mixed up. You can still see the original content, so it is not a complete disaster, but nonetheless several pixels have weird colours. Speaking about colours, the effect is most visible on black and white. Also, the artifacts when moving a window typically occur to the right of dark/bright or bright/dark transitions, hence my guess that there is some kind of overflow or underflow in blitting operations. Note that these artifacts are removed when the area is redrawn, e.g. by moving another window over it. It isn't redrawn when just moving the mouse over it, even though I have the option "HWcursor" set to "off" in xorg.conf. Also, those artifacts are really there, i.e. not just something that is outside of X's control. What I mean is that when using Xmag, changing the resolution (with Ctrl-Alt-+/-) or scrolling the viewport those artifacts remain. This might give a hint where these operations take place that create the artifacts. Talking about Xmag, I took a closer look at the pixel values of those artifacts (I assume that when you click a pixel there that it displays the RGB values). I have a background with a single colour (white, RGB 0xffffff). Looking at the pixel-values of the artefact, I see following colours: fff9bf ffd9ff ffbfff fff8ff ffc8ff ffefff ffeeff ff7fff ff3fff ff37ff ffceff As you can see, typically the G channel is affected, resulting in magenta artifacts on the white background. This runs along the behaviour on black background, where the artifacts are typically green. Note that these artifacts only occur on every fourth vertical line of pixels. AFAICT (It's hard to measure this precisely) it occurs on the third, seventh, eleventh ... lines. Further, I'm also running a Matrox card. There are a handful of bugreports in the BTS that talk about Matrox cards and display problems. I'm not sure if those are related to what I am seeing, as they lack a precise description. In case that isn't clear, the artifacts don't have anything to do with window resizing/moving per se. I also see them right now while typing some text black on white. The point is just that e.g. the rubberband resizing makes this effect much more apparent. Uli -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
