** Description changed: Binary package hint: xserver-xorg-video-ati Using EXA RENDER acceleration in the open source radeon driver, on an rv250 (Mobility 9000), certain transparency elements will get artifacts along the border of the "canvas", for lack of a better word. It's not the border of the actual image, but the border of the entire canvas, i.e. a 32x32 image, of which the non-transparent image is only the center 16x16 square, the artifact would be along the "invisible" 32x32 edges. The artifacts are consistent, in that it's always the same elements that have the problem. Ubuntu Hardy Heron, 8.04 Xserver 1.4, Xorg 7.3 xserver-xorg-video-ati 6.8 The problem has existed since accelerated RENDER has been implemented. Still persists, even in the newer Intrepid Ibex 8.10 xserver and ati drivers. Setting RenderAccel to false, or MigrationHeuristic to greedy makes the problem disappear, as this disables RENDER acceleration. It doesn't seem to affect transparency that's generated by the compositor, but by transparency that's specified by an image. Most definitely an upstream bug, but I don't know where to report it. + [lspci] + 00:00.0 Host bridge [0600]: Intel Corporation 82855PM Processor to I/O Controller [8086:3340] (rev 03) + Subsystem: IBM Device [1014:0529] + 01:00.0 VGA compatible controller [0300]: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] [1002:4c66] (rev 02) + Subsystem: IBM Device [1014:054d]
