00:00.0 Host bridge [0600]: Intel Corporation 4 Series Chipset DRAM Controller [8086:2e10] (rev 03) Subsystem: Intel Corporation Device [8086:1003] 00:02.0 VGA compatible controller [0300]: Intel Corporation 4 Series Chipset Integrated Graphics Controller [8086:2e12] (rev 03) Subsystem: Intel Corporation Device [8086:1003] The original Ubuntu reporter uses GM965, and the later reporter (with log provided) uses Q45. Bryce, when you forward the bug report, could you please elaborate the driver versions? And are you able to reproduce with the upstream driver? Focus on the Q45 issue please. The original reporter did not provide all required info so we are focusing on the Q45 reporter who said he had the same issue. Hi, I am the reporter of the Q45 issue. The driver versions tested were the current Ubuntu release driver (2.4.1-0ubuntu7~intrepid), and a driver 2.5.1-1ubuntu5~intrepid which was provided by the Ubuntu Intel Graphics Driver Testing Team. I do not have a build environment in place currently to pull in the latest upstream driver for testing, but I will try to cobble something together and let you know what happens with it. To also make sure my experience is properly echoed here, I am using kwin (4.1.3-0ubuntu1~intrepid1) as my window manager, and the desktop corruption occurs for pretty much any window that gets drawn over the desktop and then removed. Unlike with the original reporter, there do not need to be very many of them; simply opening and closing the KDE Menu, for example, will show graphics corruption (of the type illustrated in the original screenshot) in the area where the KDE Menu window used to be. This problem does *not* occur when Desktop Effects are enabled within KDE. Additionally, clicking on the desktop seems to force a redraw which removes any graphical corruption that is present. Regards, Does this go away with UXA? The zero-copy texture-from-pixmap code in EXA is flawed and will fail when the rendering for a single frame is too large. Feedback timeout (4 months). |
