** Description changed: - Binary package hint: compiz + [ Impact ] When switching focus from one window to another, the target window may become blank. See the attached screenshot, where I opened two gnome- terminals and clicked on their titlebars alternately - the issue was triggered after about 5-10 clicks. I've had this happen on other appications too, e.g. software-centre, empathy, etc. HOW TO REPRODUCE: + + [ Test Case ] + + Verification requires an nVidia GPU with proprietary drivers. The + problem can not reliably be reproduced at will, only after some time + (depending on resident GPU memory and usage) and even then only + randomly. + 1. Minimize a window 2. Initiate Scale and deactivate it again (press Super+W to show all windows and then press it again to go back to normal) 3. Click the window icon on the launcher to maximize it again. - 4. The window contents will be white or black depending on the Ubuntu version + 4. The window contents will be white, black, or transparent depending on the Ubuntu version - WORKAROUND: - Uncheck CCSM -> Ubuntu Unity Plugin -> Switcher -> Show live previews of windows in the Switcher. Side-effect: scale doesn't show minimized windows. + [ Regression Potential ] + + It is unlikely this change has the potential to introduce new + regressions. + + [ Other Info ] + + Fix was cherry-picked from the Ubuntu "Vivid Vervet" dev relase where it + has been in use for some weeks without problem.
