That's not a notify-osd specific bug, but a compiz-related issue. For example you can trigger the same kind of flashing by simply starting totem playing back some video, switching totem to fullscreen-mode and then in fullscreen-mode move the mouse (to that the on-screen UI- elements appear). That causes the exact same kind of flashing.
>From my own investigation on the issue: - on nvidia-GPU (with proprietary driver), on i965-GPU (with kernel 2.6.30, xf86-video-intel 2.7.99.1, using UXA) - using compiz (e.g. Visal Effects level set to "Normal" or "Extra") - unredirect fullscreen window enabled (default setting in Ubuntu 9.04) - flashing/flickering occurs on fullscreen windows if smaller window appear on top of them - example apps tested: fullscreen totem, fullscreen inkscape, fullscreen screensaver temp. fix: - disable "unredirect fullscreen window" in compiz - or don't use compiz but metacity+compositor - or just use plain metacity This fix I regard as temporary for the moment as not all xorg video- drivers allow "redirected direct rendering" (in layman-terms: OpenGL in a composited environment). For systems-setup though with working DRI2 (e.g. i965 GPU with UXA on kernel 2.6.30 and xf86-video-intel 2.7.x) or systems with nvidia-GPU with proprietary driver "unredirect fullscreen windows" can savely be disabled, thus eliminating the flickering/flashing completely. Once all OpenSouce xorg video-drivers support DRI2 "unredirect fullscreen windows" can be disabled by default again. Note: "redirect fullscreen windows" is a workaround in compiz to cater for the fact that DRI2 isn't common place yet. So this is nothing to fix in compiz. xorg video-drivers just need to pick up DRI2. If a user has a nvidia-GPU running the proprietary driver "unredirect fullscreen windows" can be disabled right away. -- Inkscape in fullscreen flashes when using NotifyOSD https://bugs.launchpad.net/bugs/372789 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
